Up until yesterday, I was able to edit documents I had saved in Dropbox Basic in excel or word without any issues (and without a Microsoft 365 subscription). I updated my iPad software to 15.4.1 last night and the edit function is gone. Now when I click on the Microsoft excel button to edit a spreadsheet, I am asked to install excel - however, excel is already installed (see pic below). When I click “open”, it takes me to excel where I get a note that says “This account does not allow editing on your device. For an account with full access, contact your organization about your subscription plan” (see pic below).
I have uninstalled and reinstalled both Dropbox and Microsoft office multiple time. Any hep would be much appreciated.
