Nothing happens when my husband clicks merge on his account. My other teammate can’t log into the game still. Don’t think you’re’ done with this issue. My daughter can’t merge her account. We share the same phone number if that matters. You said you removed that SMS thing, but it’s still asking for a phone number from my friends and family. They mostly use pre paid phones. Please stop. 
If you removed that SMS thing we shouldn’t be prompted to enter a number. It’s just not working when they enter one either.
