I use an app called My Medical and am using iPadOS 13 beta 6. Last night I performed a bunch of updates and today, all of my data is gone and am unable to connect to Dropbox. When attempting to connect to Dropbox it tells me my Dropbox is out-of-date, which it is not. The connection to Dropbox freezes. Please help! I have over 4 years of data missing for three people at the moment.
