The Zotero app on my phone stopped syncing with my online account, and now prevents me from signing in to my account via my phone. I am using Zotero 9; I have deleted and reloaded the app multiple times on my phone; I changed my password in my account; I updated the password on my phone. The phone app will not budge beyond the sign-in page. No matter now many times I try to sign in (using my new password), I cannot move beyond the sign-in page. How can I resolve this? I rely on my phone for photos of archival documents that I then load to my Zotero files. Thanks.
