Well, it was quite simple and I feel a bit embarrassed. LOL When I ran an update, I thought it updated all three components: Invideous itself, the companion app, and the database. However, only the Invidious and database updated leaving the companion app for whatever reason out of the loop. So after fumbling around and doing a little reading, I just so happened to look at Portainer which has a green checkmark beside the container signifying it's the current version. The companion app had an orange checkmark. So I updated again, and Jack's a doughnut, Bob's your uncle. But during my reading I came across the 'reboot hourly' admonishment that I don't believe I've seen before. Long story short, everything is fine now.
