If you have installed the app before, you should be able to open the App Store, and go to your past purchases. If you find the app in there, then it should download the last compatible version.

I have used that to load old apps onto an iPad that I can't update.

You can also upload IPA files to your iPhone using older versions of iTunes that supports sideloading saved (but purchased) IPA files. Apple now offers downloads for these older versions of iTunes, see here: https://support.apple.com/downloads/itunes

Apple also makes iTunes 12.6.x available for download, but it's hidden on this page: https://support.apple.com/en-us/HT208079 - this is the last Windows version with IPA management, but there are also other ways to sideload IPA files without needing XCode and a developer signing certificate, e.g. https://codeburst.io/latest-itunes-12-7-removed-the-apps-opt...

The question is - how are we supposed to save and archive those IPA files today?

FilzaEscaped requires you to be jailbroken.

I should have said that I was asking how users can acquire IPA files without having jailbroken their device first.

Oh, I’m sorry for that. I wasn’t trying to be unhelpful or pedantic or obtuse. I hope it’s still helpful to another.

I’ve used this to do other functions before, but not saving IPAs.

Yes, the app downloads, but then the message still shows up. It's not a phone/os problem, it's the app makers forcing users to only use the latest version.
