I have had this issue since I verified my Reddit and Twitter account with Uphold on my creator page months ago and it persists after recently verifying with Gemini. It’s been a week since I switched from Uphold to Gemini and people still receive this message when attempting to tip me:
"This Brave Verified Creator has not yet configured their account to receive contributions from Brave Users. Any tips you send will remain in your wallet until they complete this process. "
Brave Browser is up to date on my Windows PC and Android mobile but the problem persists.
