Since a recent update I've been experiencing HDCP 2.2 issues with certain apps right before commercials (Fox, ABC, etc.) on both my Roku ultra and Roku premier plus. I've reset one of them and replaced it with a brand new HDMI 2.1 cable (48Gbps). Still no change. I've tested with the different subsampling settings (4:4:4 and 4:2:0) and 30hz and 60hz. No change.
I've also noticed since the update I'm constantly getting audio sync issues on both devices from Plex. Never had any issues before until this past update. Both devices have the exact same issues.
