The fix?
Don’t even bother with this old iPad, any longer!
To get past this issue means, inevitably, having to reset the device to a new device state now, and for these 8 and 9-year old iPads, this act of the complete device reset means a certain level of operational “death”to these very old iPads, for good, after the fact.
You will no longer be able to retrieve many of the older third party apps that are installed on these older iPads any longer from the Apple iOS App Store for good now!
If you never, ever backed up this device ever to both a new and older version of the iTunes application for Mac and Windows PC computer, where you could save the data and an older iTunes versions where you could still save both the actual apps AND app data, as well, any iOS device restoring processes, that end up happening to these old iPads, will render these old iOS devices nearly useless, now!
These older iPad models are too old, now, too underpowered and completely incompatible with any of the current and future versions of iOS/iPadOS.
Sorry, but it is what it is, today, in the year 2020!
Apple supports new iPad models for up to 5-6 years with third party app developers supporting these iPads for another, additional 2-3 years after!
So, that is a total of between 7-9 years of iPad/iOS support!
ALL older iPad models, like the iPad 2, 3, 4 and 1st gen iPad Mini have, finally, reached this support limit!
These old iPad 2, 3, 4 and 1st gen iPad Mini models are, virtually, 8 and 9-years old, now.
The amount of older, compatible, available apps for these old iPad models has dwindled significantly since the beginning of 2020!
Getting older versions of apps for these old iPad models, initially from Apple’s iOS App Store is getting very difficult and very problematic and this issue is getting, painfully, much worse, now, in 2020!
As of the beginning of 2019, many, MANY third party app developers are all more quickly and completely permanently dropping older app support for all old 7, 8 and 9-year iPads that are running 2-3 year old and earlier iOS versions ( iOS 10 and earlier ).
Third party app developers are removing all of their older, legacy versions of their apps from Apple's App Store servers, now.
Third party app developers no longer want to support these 8 and 9-year old or older iOS devices, any longer!
Older versions of apps are, soon, going to be gone for good, now!
These old iPads are now reaching their complete end of life and support cycles.
So finding older versions apps for older iPads, while still possible, currently, will be a very tough challenge, now, in 2020.
Old iPads that can no longer be upgraded/updated will have NO MORE APPS AVAILABLE for initial download, at all, soon, from the Apple iOS App Store, for such old iOS devices in the very near future.
Older versions of apps for these older iPads will be completely gone, at some point, in the very foreseeable future.
Old 8 and 9-year old iPads will be pretty much obsolete by the end of the 2020 year!
Again, it is what it is, today, in the year 2020!
You will never get any more older versions of popular apps for these old iPads, any longer.
The apps that these old iPads already have on them, and still work, will be the apps these iPads will be stuck with!
Basically, these old iPad models are just good for FaceTime and somewhat limited Web browsing via some other, more up to date third party Web browsers and NOT using that nearly 4-year old iOS Safari Web browser.
