Apple id on ipad mixed up can't install apps

hi!! i seem to be locked inside a weird loop. my appleID is as not originally on this iPad. it was used with different email for work originally. Let's say that's called work@email.

now i'm logged in as myself(my personal email and cloudID)

i go to update apps in the app store - says my password is wrong.

i go check, correct password. wrong ID. it's trying to log me in as work@email, but i'm logged into ipad with personal email!! i can't see where to switch and get this old work@email out/off ipad so the whole thing is under personal email and i can update apps.

im guessing to log out of icloud - but i am already!! according to the ipad - i'm already logged into icloud with personal ID.

im stuck - is there another spot i need to remove this old id from?

thank you.
