At this time SafePal is not fully supported. User can check positions that are on SafePal wallets, but can not login to PRO if their Vision is in their SafePal wallet.
It may be worth trying to login through WalletConnect to see if this issue has been resolve though.
A workaround solution is to get your Vision tokens, Vision LP position, or NFT in a separate wallet like Metamask and login with that wallet. Once logged in, you can add the SafePal wallet address and track those positions with your full PRO access.
