Not sure if this is necessarily a bug or not but I was approaching KSEA going to enter the left downwind due to winds. So I connected to the Tower which was in use at the time and got given landing permission as you do. However as I’m in the downwind the controller disconnects so it goes to Unicom. I am then repeatedly spammed with messages telling me I’m in an active airspace and to contact Tower despite it being shut. So I had this spamming for most of my approach despite no Controller being online.
I tried to disconnect and reconnect to the server by leaving the app then quickly re entering but there was still no controller.
May have been a problem on my end and if you were the controller I apologise for not being able to connect.
