Hello, I'm getting an error when I try to publish a folio. The dialog says the Product ID is invalid. I have tried different IDS and I'm still getting this message. It also appears when I try to update the status of an already published folio.
This folio needs to be published in next hours.
This issue has been identified by the engineering team and will be fixed soon.
In the meantime, you can use a different productID is you want (for free content). make sure the ID consist of lowercase characters/numbers/dots ; for example org.tukker.dps.demo.dec13
I also have the same problem, along with a few others, as it's the first time I'm submitting the App to the App store.
1) We've created a multi-Viewer App, free, with a lower and uppercase App/ Product ID (Bundle ID).
2) We've initiated the APp submission process on the App store.
3) The folios to be published will also be free. So we have signed in to the Viewer Builder with our Publisher account, and in the Adobe ID for the Title in the Viewer Builder, we've specified the different Adobe ID of the user used to create and Publish the folios. Both These Adobe ID's are different.
4) We sign in the Dashboard with the Adobe Id used in the Title field of Viewer Builder, and then Publish the Folio as Public.
5) There's an error that read - "the Product ID is invalid", apparantly because of the issues discussed in the posts above. Since it's a free folio to be viewed on a free App, we change the Product id to small case letters. Thann I'm able to Publish to Public.
6) Now on the Developer.ipa File installed on my iPad, there's no Download or update available, which I presume should be there. The manual for iPad Publishing Process explains the sandboxing process, but it's only for Retail issue. Do we need to sandbox the free Apps and Folios as well? Should the free Folio be available for download in the developer App when Published as Public? In case of Free folios, how can we change the upper case App ID with the Lower case Product ID on dashboard, as explained above. Are the App/ Product ID's not case sensitive?? Please correct me in case I've done something wrong.
The productID is not the same as the BundleID. The BundleID identifies your applicaion, a productID identifies your individual folios across multiple systems. For example org.tukker.dps.dive.2011.11 ; this would be the productId of the folio that I publish (free / retail) and in case of retail also the productID of my In Application Purchase at Apple / Android. The viewers will match these up to determine pricing.
I would suggest to read/work through the iPad publishing companion guide to match gainst your current process.
The main steps
1. Create a application Account within your account management environment for your publication (for example firstname.lastname@example.org - make sure the emailaddress does exists)
2. Create your folio content in Indesign within the account created in 
3. Go to the Folio Producer web interface and publish the folio as 'private'
4. Login to the Adobe Content Viewer (with the account details in ). There should be at least to folio's. The one with the blue bolt is the one on the Acrobat.com environment, the other is the one on the distribution server. Check if the folio on distribution is correct
5. Go to the Folio Producer web interface again and republish the folio as 'public' (free) - (for retail, see iTunes Connect on how to create InAppPurchases) - more advanced procedure
6. Login into Viewer Builder (using any viewer builder account)
7. Create a multi folio app and in the field 'AdobeID for TItle' enter the credentials you created in step .
8. Finish the app creation and install the development app on your ipad
9. The folio published in step  should appear
If this works, submit to Apple or any other marketplace..
With kind regards,
You don't need to use the sandbox for free folios -- only retail. For free folios, the Product ID you use doesn't really matter. And don't worry about the uppercase App ID you created. You never specify the App ID on the Adobe side.
By the way, this bug that doesn't allow uppercase letters in the Product ID should be fixed soon. In your case, with free folios, just use lowercase letters for now and you'll be fine.
To give a little background, Apple allows uppercase letters in Product IDs but Android does not. If you're submitting the same app and folios (or folio renditions) to both Apple and Android, the Product ID with uppercase letters will be valid for Apple but not for Android. To avoid this Android problem, Adobe made the mistake of requiring a lowercase Product ID. The new approach will be to alert users if a Product ID contains uppercase letters. If you're publishing only to Apple, you can ignore the message. If you're publishing to Android, you should change your Product ID.
