Downgrade? For same App Version on iPhone & iPad

[VortexSpin]

My iPhone 7 plus has the DJI Go 4 app version 4.1.2 and functions perfectly with the a Mavic.

Somehow my iPad Mini 4 ended up with app version 4.1.5 on it. Would like to stay with 4.1.2 on both the phone and iPad.
Can I downgrade ? the iPad to 4.1.2 without messing up the firmware for the Mavic ?? Etc.
Like the fact that things run well on the iPhone 7 plus not looking to muck it up. The database on both devices is 01.00.01.04 for the record.
Anyone?
Thanks in advance.

You can reinstall an older app version if you had backed it up on your computer, or by using this method if retrieving older apps if you didn't.

Thank you. I'll check into that. Also forgot to inquire...do I need to? What's going occur if I go to use my iPad with a different version running on the iPhone/Mavic ?

Nothing.
