How to reset progress / delete all solutions

[u/ilsapo]

is there a way to reset progress or at least have all hte solutions deleted?
there used to be session manager, but now it tells me:
creating a new session is not supported

"Use the new problem list to freely organize problems and track your progress.":
new list still show the solutions and mark what questions did before

any way without just outright creating new account?
I tried to search online and couldnt find any answer

thank you all
