Antwort auf: Philips: Neue Firmware für 2019/2020er TVs mit Android TV 11 (TPM191E: 201.0.248.227)
@Nick:
Did you do a factory reset and then reinstall your soundbar? Are you using the bypass option, if your soundbar can handle it...?
Before you downgrade, I would check all these things first.
If you do want to downgrade, take a look here - but everything has already been explained in the previous posts and can actually be read there.
