Can't pair to with Bambu Handy after servicing P1S

When the P1S was new this wasn’t a problem. But now, after servicing the P1S I had to reset for some reason and I can’t pair to with Bambu Handy. It just has and endless “search” for service which is 500mb wifi and I’m standing next to the printer.
Servicing the P1S was a nightmare. Now this?

Suggestions please.

Solved. I had to “disregard” old printer on phone bluetooth.
