Some days gone since i flown the ATR last time, but never had this problem before.
Running the ATR in Hotel-Mode, call the GSX pusback, truck arrive and all is as usual. After truck is connected and i assigned a dirction, i get the "release parking brake" info. After that i release the parking brake (push it complete!!! forward) and release the chocks in the EFB. The pushback starts and then the nose goes up until the tail strikes on the ground, i get the message: "release parking brake immedietly".
But it is relesed and the chocks are off.
Tryed it at severel arirports and after a restart as well.
Whats wrong??? Any idea???
