Hello. Old timer here. Decided to open my wallet after many years. Updated to V3. Now each time I open the app I get this:

I can see all my DMDs but this error message is annoying. What can I do?
a v2 wallet.dat should not be used with a v3 wallet
export the private keys that hold coins and import them into a new v3 wallet
lot stuff is covered on this community driven faq page
