Migration from STM32WB55RG to STM32WB5MMG

I have a stable BLE application on STM32WB55RG. The application uses a Custom Template, has one service one characteristic for notification only, and uses Public Address for Advertising. I send the notifications to Central with an interval of 100msec, triggered by a Timer. The Wireless Stack was generated with STM32WBCubeFW V1.22.1 under CubeMX 6.14.1. Everything is fine in STM32WB55RG. But after migration to STM32WB5MMG, with absolutely the same related to Wireless stack parameters, it works only advertising. Connections always fail! Any suggestions?
