FP5 sometimes charging, sometimes not

I*m quite satisfied with the new FP5. But the Fairphone 5 has problems charging. Sometimes it does not charge at all, sometimes the charging process is cancelled. Removing the charging cable and reconnecting it eventually solves the problem. I would rule out the cable as the cause. It is an original FP3 adapter + cable and works with the FP3 without any problems. What is noticeable: the pin on the Fairphone wobbles. I have raised a support ticket. So this may be only an information for anyone with similar problems.
