Re: I think it is due to new naming scheme since builds end with something like "-9906e21a06a0"
That's the commit hash, and it is part of the app's file name but not its version name (in the .apk).
Sorry about that. We never had a way to handle that in the xversion files.
Please remove this suffix if there, it's always at the end, 12 hex characters, and there is always a "-" before it.
