I’m having an occasional problem with Christmas cards on the android app. Sometimes no-one shows up on the contacts list - all my contacts are in the ‘contacts you can’t invite’ list with [you need qualities]. I’ve checked that I have cards and turns - do I need suspicion/nightmares etc or is this just a bug? I’ve had a few problems with the app being glitchy (although I still LOVE it) so I’m thinking bug…
There shouldn’t be any requirements on either end, so this sounds like a matter for support.
I had a similar issue where I was in the send a christmas card screen, but it was for a card I didn’t have the proper airs of london for. Going back and trying to send a card again fixed it. (this was on the browser version though, so I’m not 100% sure it’s applicable to your problem)
