THE BASICS: I have tried all day to get a football game ticket to download to my Samsung S10 onto my google pay account (only option).
I have:
Made sure your default payment method on your phone is Google Pay.
Made sure NFC is enabled on your phone.
AND battery saving is NOT on!
I get a white screen from G PAy - "Something went wrong. Please try again"
But it still doesn't work! My solution so far has been to get a friend with an iPhone to download the ticket for me 
Secondly when logging in from Yahoo email to Gpay - I lose the keyboard. I have got around this by making a note and cutting and pasting the username and password into the screen - this at least I can overcome, but is also painful.
@ronan888: You mentioned that Power Saving Mode is not enabled, but the icon is showing in the screenshot above. With this in mind, please swipe from the top of the screen to the bottom, then again to enlarge the Quick Panel, and tap on Power Saving Mode so it greys out. Also, the orange N in the bottom right corner may be drawing your attention to an available update, therefore I recommend following the icon trail to see where it leads. Let me know how you get on.
