On Acrobat mobile, I cannot open any folder in "My Drive" that was shared with me by someone else. I can open them through "Shared with me", which indicates it's not a permissions issues (but is annoying because it's a huge unstructured list of every file and folder anyone has ever shared with me). The error is "Could not open <folder> due to an unknown error. Please try again later." Anyone know how I can view shared folders in Google Drive on Acrobat mobile?
I should mention that I tried rebooting my device, signing in and out, removing my Google Drive account and adding it back, re-installing Acrobat mobile, and sorting by both name and date (which fixed a related problem for someone else). None of these solutions worked.
