The issue you are facing:
I had a nice working version of 12. Today I changed update to daily and found a new daily build of version 12. I clicked to install and it seemed to install fine. However when clicking to proceed I get this message
The files of the app Gallery (gallery) were not replaced correctly. Make sure it is a version compatible with the server.
