I can only repeat my last request:
Of course, if you made a more precise report, like the airport used, the gate used, the pushback direction selected, if you have a custom profile, if you have a custom pushback or ANYTHING that could allow to REPRODUCE your problem, we might have a better chance to understand what's happening in your case.
Which I posted because, of course, I tried the pushback with multiple planes and different airports, and I couldn't find any issues so, clearly, it must be something specific to a certain combination of airplane, airport and gate and kind of pushback used.
