iPad2 can'r remove Apps, they wiggle but there is no x

Native iOS Apps cannot be deleted - whereas third-party Apps installed from the App Store can be deleted. Be warned that any Apps that you successfully delete from your iPad2 cannot be reinstalled.

You may need to consider that compatible Apps for older models of iPad are no longer available for download - as App Developers have dropped all support for 32-bit devices and many for iOS versions preceding iOS11/12/13. As older versions of Apps are removed from the Apple App Store, you’ll not be able to (re)download or install them - which may severely limit the usefulness and utility of your iPad. As such, you may need to consider replacement of your iPad with a newer or current model.

If your iPad’s internal storage is full, your only option is to better manage the storage that you have - and delete unneeded data.
