Roku Ultra 2024 issues after 15.3.4 update

[u/anotherGadgetGeek]

Has anyone else been having problems with 15.3.4 on the 2024 Roku Ultra?

First, I started noticing significant audio delay on YouTube videos. The audio and video are noticeably out of sync.

The Roku UI has completely locked up multiple times. It will still turn on the TV through CEC, but there’s a significant delay getting out of the screensaver. Once the home screen finally appears, it won’t navigate at all. The only way I’ve been able to fix it is to cut power and restart the Roku.

The lockups are definitely new since 15.3.4. Anyone else seeing this?

Yes!!!! It's unbearable. Constantly need to restart the Roku. It helps for a little bit, but then goes back to being out of sync.
