Changing back to 1 star. Discovered that if I keep a doc open in the background on my phone it always becomes "view only." Uninstall, clearing cache, restarting phone, logging out and back in. Those basically never work. I have to copy/paste into a new doc and when that doc runs into the same issue, I copy/paste again. This is absolutely ridiculous. I shouldn't HAVE to close the app to keep it working. I never used to and I've been using this app for nearly 10 years on my multiple phones.
