After contacting Ground and receiving taxi instructions, I was instructed to switch to Tower. I tuned to the correct Tower frequency, and the frequency section showed that I was connected to Tower. However, when I requested departure clearance, the controller kept telling me to switch to Tower as if I was still on Ground. I retuned to Tower multiple times, but the issue persisted and I was eventually disconnected by ATC. I also tested this at multiple airports with the same result, so it doesn’t seem airport-specific.
