Bambu Lab P2S does not resume printing after a power outage.

After 3 hours of printing—with one hour remaining—the power cut out and the printer shut down, only to restart automatically after about 30 seconds to a minute. Upon restarting, no prompt to resume printing appeared. I made multiple attempts to start a print, get past the first layer, and manually cut the power. I tested with and without a USB drive, and tried pausing the print before turning the machine off and on again, but nothing worked—there was no message to resume printing. Is this a firmware bug, or am I doing something wrong? I couldn't find anything relevant in the printer settings.
