Re-install old app

Does anybody know how i can reinstall the old app?
I have the kickr bike and not all of the functions are supported in system.
Unfortunately my ios is on autoupdate and the app store only shows the new app.
The minions are working on a fix but in the meantime the old app is needed

You have to restore your iphone or iPad from an older backup that had the SUF installed. However, if you do that, you’ll loose everything from that old backup till now.

And turn off auto update or you’ll revert to Systm again.

I did it with FulFaz last year.

Thanks Sir - I’ll give it a try
