My photoshop (ipad) tweaking fr, got any help?

I am using an ipad 9th gen, and I am currently under the JAMF restrictions by my country's Ministry Of Education, (SIngapore). So I have tried uninstalling and installing this app 6 times already, and I tried signing in via Adobe and google, but it keeps leading me here. I can't open the restore your purchases due to restrictions, and it just stays here. Is there anything I can do, or should I just stick to photoshop express that's already there? They all deleted the App Store btw
