This has happened a few times now. I leave a recording (3+ hours of football) paused for a few hours, and when I return and try to resume, it errors trying to load the recording. “Retry” results in the same error after a spinning circle for about a minute. “Cancel” and return results in the recording being deleted!
Using Amazon Fire TV Max stick and firmware 2.2.56 (recently installed). It previously happened with version 2.2.54.
