Everything is going great on my OLD iPad. But I want to borrow my wife’s new iPad Pro M4 chip because it has a nice BRIGHT screen.
When I try to download ST3 and to get or find the “account” option, I can’t find any way to see it. So how can I get my ST3 loaded on this other computer?

Do you mean how to restore your purchase? Go to Settings > In App Purchases > Restore Purchases. This will only work if that device is running with the same AppleId you used for the purchase or in an iCloud Family.
