Photos Companion App Problem:

It worked well on my Samsung but not on a friend's LG android. Tested this on two laptops, same problem on both.

After selecting photos to transfer with a checkmark and selecting "Done", the LG screen came up a message that was so fast I couldn't read and the QR window popped up again. Looked to see if a transfer was made, no pictures transferred. Tried several times.
Is there a setting in LG phone that needs to be changed?

(Hope that I posted this question in the right category)

Help is appreciated,
