ATC seems to respond to other traffic (AI traffic) before they respond to me when multiple aircraft transmit their requests, even when I transmit before them. In a busy airspace I’ve had to wait a minute or two while ATC talks to other AI aircraft and they respond, before ATC can come back to me. AI traffic could have a bit of courtesy to wait until the ATC responds to the user, and ATC should respond in the same order of transmission instead of skipping the user to deal with AI traffic.
