For about two weeks now I have had to delete and re-install my Adobe Scan app because it loses my subscription information. Thus it won't save my scans to the cloud. I hae lost work, which I have had to repeat. Now I am more vigilant, checking the subscription info in the app before starting a scan. If it's gone I delete and re-install. Must have done this five times in the last two weeks.
Hope you are doing well.
