Is this instruction necessary for installing every new update?
As far as I understand that it's good to have latest update installed. This keeps you safe from any unexpected risks. By the way, I am still having the same problem. I think it's not about the version I have, it's something to do with the unconfirmed tx I have. I am just not sure. I am still waiting for TryNinja.
Cheers :-)
I didn't ask about installing new update. I asked, Is this necessary Uninstall the previous version & deleting all appdata files before installing new update?
