How to install older version of app, as the new one has problems
On a iPhone 5s I need to reinstall an older version of an app, specifically FlirOne (thermocamera), since the new versions do not support any longer the version 1 hardware I have. I read that the older version could still be on the Apple server, but no "trick" I could find works.
Any clue?
Thanks
