when i try to submit a run, it just says "you must be logged in to submit a run" even though i am logged in.

Try logging out, clearing cache/cookies, logging back in

If that doesn't work, try another browser?

I have the same problem....

Try reloading the tab on the page that says "you must be logged in to submit a run". It worked for me.

):

I have the same issue and tried reloading, another browser, with private mod and with cache deleted... Nothing changed.

oh that is weird mine worked when i reloaded i was at it for 10 mins i felt dumb

Make a new account or change your email

Making a new account is unnecessary.

unfortunately that's being reported more and more recently with new accounts, all the above fixes except for making a new account are sensible to try and are known to have some effect though :)
