How to handle multiple save states on mobile?

I have a mobile app that I am working on that allows an account owner to manage subscribers on the account. From one screen, they will be able to set "limits" using a slider on the account. Each input/action from the account owner is a service call.

The initial UI was a batch edit and save mode where all the changes are made and one service call is made. The issue with this flow is that since everything is its own call, some elements could potentially fail and some pass which would mean multiple success/alert notifications at a time.

So the alternative is a save state for each individual subscriber where we force the user to pay attention to each individual save to make a change.

Does anyone know of a better experience in this case?
