When I was trying to change my phone number, a message is appear 'OH-OH! Some error occurred. Please try again later' What's reason for that?
Hey @joannalili! Philippe here. Welcome to the community.
I'll be happy to help you with that! Have you tried a different browser for that?
If yes or no, you can also try to clear your browser's cache and cookies. That may help with that.
