Looking for a simple process for installing a prior release for a first time user?
Scenario:
Version 2.0.56 is stable working version
Version 2.1.# has introduced bug that blocks survey submission
see
https://github.com/Esri/Survey123Community/issues/629
New employee is required to install Survey 123 on iPhone and begin collecting data
App Store will only install Version 2.1.6
Employee can not work without Version 2.0.56
