My imac system is macOS High Sierra iOS10.13.15 and BTT version is 2.5.30.

The mouse1 is normal using in the other apps,but can not be find in BTT.
I tryed the old version of BTT ,it can be normal for about few minutes and still can not fix it...

what to do now.....

Bought a licence some time ago and I've just got a new iMac with a new magic mouse and get the same thing.
Any solutions?
