I'm only gonna use an example, but if a setting like this shows up, then that means it's* able to be moved to the SD card. Not all apps will have this setting, so if you do not see this feature on the app you're trying to move, it will not be compatible for transfer.
Unlock developer options by multi tapping build number in about phone/ software information. Than you'll see developer options in settings. Look for and check force allow apps to be on external.
