Mounted RF100-500mm lens is not stable

I have an RF 100-500 lens that I use with an R5 mk2 (previously with a first gen R5). A couple of weeks ago I noticed that when I am holding the camera the lens actually moves after being mounted. I tried the lens on a different camera and it's loose...

Hi, I have found myself in a bit of a predicament, I’m in an upgrade process, from Canon 2000D. I had my mind made up on the Canon R7, which will be a great transition with all my current lenses, by just adding the EF to RF Adapter. But now I found a...
