T-Cross: hands-free device loses connection to mobile phone

Hello together At the end of last year I had to get a new (used) car, because a red light lighter shot my beloved Ford together.. The choice (didn’t have much choice) much then on a T-Cross 1.5 Bj 2022 In the beginning the hands-free device with my Samsung S22 Ultra worked excellently. However, for about a month it does cause considerable problems. Constantly the car loses the hands-free connection to the mobile phone, apps (Spotify & Google Maps) work wall-to-wall free. It comes in some minutes “Mobile phone has lost the connection” (music runs on via app). I’m not quite sure, but it started as an update for the T-Cross. Or when the We Connect Plus went out? Much so simultaneously together. Have the mobile phone been disconnected from the car several times, the Android software de/reinstalled, cache deleted, etc.. no improvement. Does anyone have the same problem? Is there any remedy? Is it on the We Connect P. lus and I have to buy it again? Thanks for possible answers
