Does the Adguard for Mac receive automatic application and filter updates, or do I have to regularly hit the check for updates and check for filter updates buttons?
Will it ever be possible to block ads in these apps, possibly with root? Out of curiosity, why is this such a difficult task on Android, when it can be easily done on Windows and macOS?
I experienced a similar problem with allo.google.com/web, and the solution was to add instantmessaging-pa.googleapis.com to the https exclusions list. See if that works for you.
