Cards only showing in Mac OS app !?

Hi Everyone

Here’s an interesting one I can’t wrap head around. A little bit ago, can’t be specific as just moved house so only picking up again recently, quite a few of my cards have stopped showing on anything other than the Mac OS app!

Cards such as mini media player, spotify, upcoming media no longer show on safari on iOS, Chrome on iOS, Chrome on Mac OS, Microsoft Edge on Win 10 but all still show and respond on the Mac OS app (2021.11 on OSX 10.15.7).

Can anyone think of why this might be?

Can’t imagine what’s so different about the Mac OS app, esp compared with the iOS app.
