Remove original Sonohealth app before d/l Sonohealth 2.0?

Got new machine, d/l’d Sonohealth 2.0. Had trouble getting it to sync, so deleted 2.0 & loaded original older app. EKGraph synced fine with that app and seems to work well. How should I proceed if I want to d/l the newer 2.0 app or is it worth it?

I’m running version 2.0.12 on my Samsung Note 9 and it runs good. I just updated from the Play Store.

I would think Apple works similar.
