App Store-iPad

So, recently I got a 9th generation iPad for Christmas. When I first got it, I had used a different iCloud, but i had to change the iCloud on the iPad to a different one recently. When I did that, everything worked fine but when I go to update an app or download one, it tries to have me put the password in for the old iCloud I had on the iPad and not the new one. When I press cancel nothing happens, but if I put the password in for that iCloud it tells me to go to settings to fully set up iPad with that iCloud. I don’t want to use that iCloud for this iPad anymore. I even restarted the iPad, logged out of the iCloud on my settings and in the App Store. I also restarted the app and tried to login with the new iCloud. It tells me I’m logged into the new iCloud but if I press account on the App Store and press update all apps it still tried to get me to do it through the old iCloud that I’m no longer using for this device. I’ve searched up videos on what to do. Nothing the videos suggest work so this is my last resort I hope someone can help.
