MJPEG Integration Not Supported - Is it my missing OctoPrint Integrations?

I did the latest upgrade to HA and got this:


Then I went to the Devices and Services page to see my integrations and I see this, which includes ignored or disabled integrations:

I had two OctoPrint integrations in this so I could control 3D printers through HA. (This is an important feature to me, for my business.) They’re gone. Don’t see them while using or not using any filters. They did have webcams enabled, so I’m thinking it may be them.

It’s really frustrating to see things like this just disappear during updates without any indication of what I can use to replace it or any help on that. What’s causing the error message? Is it an OctoPrint integration? If not, how do I track it down and what can I use instead?

(Once again, one of HA’s frequent updates has meant I have to stop what I’m doing for work and take time to figure out what’s gone wrong and feature I counted on is now gone. It’s frustrating I have to take time, on what seems to be a weekly schedule, to deal with HA updates of one kind or another. Every time I do that, I sit on edge, wondering if, when it comes back up, everything I had before will still be working when the system finishes upgrading and rebooting.)
