I have an Adobe account with the Photography plan, Acrobat Premium, and the Adobe PDF Pack. However, with every iOS update I have to log back into all my apps. Since the most recent update, to iOS 13.6, I'm unable to login to my Adobe account on the Adobe Capture app.
I'm not sure if this is related, but I was also receiving a "No Internet Connection" error whenever I tried to log back in on the Lighthroom App even though I had full WiFi and Celluar. That issues seems to have magical resolved itself.
