Chrome uses quic by default that runs over udp.
Probably they changed the behaviour and Palo AppID does not match any more.
Temporary workaround might be to disable quic in Chrome.
You can't decypt quic anyway so you loose visibility when users access Google services with Chrome so disabling it might be good idea anyway.

Had the same issue, Palo TAC advises that the content team is working to resolve the issue. Watch this space for an emergency release.

Version 625
Notes:
With the most recent version of the browser Chrome, Google updated their experimental protocol QUIC, which caused the "quic" App-ID to be misidentified as "unknown-udp". With this content update, Palo Alto Networks is releasing additional coverage for the "quic" App-ID to include the changes made by Google.
