A number of us are having the same problem, being reported on several threads, with no solution in sight. Every finding you have described is exactly what everyone else is seeing. If you have another computer and a Dropbox or OneDrive account, you can use those to access your Creative Cloud files, moving them on and off of your iPad using the Share function in PS Touch. Lots of extra steps, I know, but it does give you file access until Adobe can fix the issue, whenever that will happen.
Thanks for the info, I appreciate it. I just wish Adobe would fix my app and restore all of its functions.
Having the same issue here. And I have an iPad air with plenty of space, so hardware performance shouldn't be a problem (my iPad air runs everything so much faster than my old iPad w retina display...)
The problem with your solution is that since Adobe is offsetting the price of the touch apps by offering a free month of cloud to CC customers who download three "touch" apps, I *need* to log into my creative cloud in order to access the promo. When will that happen?
Anyone from Adobe around who may be able to shed some light on the issue?
I FIXED IT!!!
So it seems that at least my issue may have been a RAM memory problem. And no amount of restarting was fixing it...
Now, this may sound shady, yet it did it for me so I thought I'd share. There are a couple of free apps that "reallocates" the RAM in your iPad or iPhone. I tried one that didn't seem to fix the issue. Then I tried another and TA-DA! Not only PS Touch didn't crash, but it synced and remained stable. Beautifully!
Below is the link for the free app I used. You can use this or do a search for a similar RAM allocator. Once the app is downloaded, get it to reallocate your device's RAM a couple of times, it's pretty self-explanatory. Then restart PS touch.
I have an iPad Air and I tried your app suggestion. It said I had no junk and I reallocated several times. The results are still the same for me. The Photoshop touch app still crashes if I am connected or try to sync with the creative cloud.
I even tried another app with the very same results.
