After choosing type of card (visa/mastercard etc) i got blank screen. Soft reset of phone and FR945 does nothing, nor reinstall of the connect app...
So it is random :( Just keep trying once a time.
stil does not work for me. :(. I tried several times today.
Also not working here.
Same problem. Android and Fenix 5 plus. Of 50 tries it suddenly work one time (but that card wasn't supported). Very annoying trouble.
Android 9, Vivo active 3,blank screen when trying to add card back under visa. Running man and screen goes black!
Finally, I've managed to add a card. It *might* be that Chrom update (from Google Play) helped.
Still not working on my phone. :(
