My daughter sent me an invitation to add and edit a folder that she created in her Dropbox account. When I try to accept the invitation, I receive an error message that says "Could not add to Dropbox". There is plenty of space in my account to accept this folder, and she and I have shared many folders in the past without any problem, so this came as quite a surprise. I have checked settings, restarted my phone, none of which helped. I have the Android Dropbox app running on my Google pixel 6 pro, which has never had a problem accepting a folder before.
