I’m using Vimeo. The splash screen is auto adding even after being deleted. I do not want to have to manually set every video to the custom screen we want to use.

Sorry, thought you had access to that in my account.

Also I’m using Firefox 96.0.2 64-bit.

I’m using Rhythmo, however it doesn’t seem to be related to that. I disabled all the plugins EXCEPT for FV Pro and FV player and switched to the Twenty Twenty One theme and it still happens.
