Thank you for the suggestion TheDreadPirate! I ensured my FireTV is up to date. I then installed the 0.16-beta5 version a try, and unfortunately it still behaves exactly like it did on the previous version.
Thanks tmsrxzar, I have a FireTV Stick 4K - 1st Gen. Sounds like I might need to upgrade then? Is there any way to transcode the data automatically so this older FireTV stick can handle this content?
