Is there any update on this? It has been over 5 months. This seems to be related to Android's Pie release version 9 and not specific to my Pixel 3.
I really do want to continue with HanDBase, but at this point the only thing I can do is overwrite what's on my phone! Thus I have to manually make updates twice! First on my device, then on my PC. As I have multiple devices, I really liked the syncing issue so that I don't have remember where I updated a particular table on which device.
I would be more than happy to run any Beta/Testing versions to help get this resolved.
