Please never use Stable Fallback unless you have to. It is very outdated and is no longer being supported.
Make sure your firewall and antivirus aren't blocking osu! From doing anything and when waiting for a score to submit don't restart or close osu! at all or the score will be completely lost. Make sure you have a clear internet connection and if that doesn't work try using a VPN
well it happened again because i thought it was just me messing up the password so i tried the fallback because I'm stupid and it said that bancho needed to check my authenticity before i even logged in so after i did i went right back to the latest and now same problems scores not received, osu direct breaks, and scores don't submit so i don't think its my ip because my brother's osu is working fine so does fallback break osu that much? and if so why hasn't it been removed if it does break it that much?
