Pain on the butt. Too many sites can’t find the ones I need. Microsoft is much easier

Huh???

Every time I try and set it up it sends a code number, doesn’t say what it’s for and then keeps changing it.
One last chance then it’s removed and some other security protocol for me

Needs an “unselect all” when exporting.

I thought that this app is good and solid. However I do think the fact it’s hard to link across devices could be improved.

Good
