CameraConnect problems

My problems with Canon CameraConnect app have never disappeared. I've posted questions before and still wonder whether I could ever have the app function properly.
I've removed and reinstalled the app many times and always struggle to make it work, but always malfunctions. The only reason I added it to my phone is to get my photos tagged with GPS info. I went for a walk today and the first 3 or 4 shots got tagged, but the rest were not.
I have the same issues with both my M50 and my M6 Mark...
