I can’t access my own file. I am the owner if this file and I have a paid account. I have been using this file for the past 4 hours and suddenly it showed “you don’t have access to this file”.
Hi there, this has been escalated to Engineering, and we believe this now to be resolved. If you are still experiencing file access problems, please let us know!
Thanks,
Toku
