I seem to be missing some protect plan features. Am I wrong?

Hi all,Until recently I had a single camera on the basic protect plan.When I moved house, I bought additional cameras and upgraded to the plus protect plan. I was initially placed on a trial, with billing to occur 21 March - all good.Last weekend, I purchased the alarm and set it all up. However, certain features are not available to me in the app. For example, if I go to Control Centre, Settings, Alerts and try to set up real-time alerts for my alarm, I get the message “You need a Ring Protect Plan”.I spoke with numerous chat agents. No help.Called via the support number and the guy told me it was because I did not have assisted monitoring enabled. And effectively forced me to enable that (which I was not planning to do until next week as not all sensors etc. are up yet due to decorating).With assisted monitoring enabled. Nothing has changed.Also noticed today that when I go to devices, base station it shows the mobile signal icon with a strike through - another thing that seems odd.Pretty fed up of speaking to multiple support agents on this now. Seems to me that the trial that I was given for the cameras is still active and is not allowing the protect plus with alarm trial to be recognized.Anyone had similar and managed to resolve?
