Transfer Cam plus to a new camera

I currently have 3 year-long subscriptions and 1 trial that is soon to expire. I am retiring one of my 4 cameras and want transfer that subscription to the new camera (the one where the trial subscription will elapse). Not sure how to do that. Also, does Wyze have a support number to call or chat?

Subscription management used to be in the app (“Account” → “Services”), but now it can only be done on the web. Why can’t Wyze show a link?
