All of a sudden my Android phone won't let me open PDF attachments from gmail. I received an email with a pdf attachment, i attempted to view it and the adobe acrobat reader have me an error, starting it wasn't a valid file. I shut down the adobe program and went back to gmail and selected the same email attachment that had previously not been able to open because it said it wasn't a valid pdf (but it definitely is valid) and it worked, I uploaded the attachment to dropbox then switched back to gmail, deleted the email with the uploaded attachment and proceeded to open the next email and PDF attachment, when I attempted opening it, I got an error stating it wasn't a valid. This keeps happening. Please help. I'll try restarting my phone and see if it still happens.
You can only view pdf files using Adobe Acrobat Reader app on your phone. Could you please share your problematic pdf at firstname.lastname@example.org so that we can investigate the issue?

I uninstalled the gmail updates for the Android app, everything is working fine now, it's a gmail issue. PDF had no problems. But I'm concerned about future issues. Anyone else having this issue?
