Is the previous version of Jotform iOS app still available?

It appears there has been a complete redesign of the app. It does not have any of the functionality that I use it for. Where can I find the previous app?

I was on version 5.6 and now it is version 1.8.4? Is this an entirely new app and if so, how do I get the old one back?

I am assuming that you're referring to the new mobile app.

If you still have a copy of the old app on your phone. I think you can still use it. Unfortunately, you cannot download it anymore in the app store.

May we know what function are you looking for?

I hope this information helps.
