Old ipad application setup

Be aware that the iPad mini1 can only be updated to iOS 9.3.5 (WiFi Only models) or iOS 9.3.6 (WiFi & Cellular models). This will affect availability of Apps that are compatible with your iPad.

Apple ended update support for the iPad mini1 in September 2016. Your iPad cannot be updated to iOS 10 or later major versions of iOS, as the internal hardware does not meet the minimum technical requirements for new versions of iOS/iPadOS. This limitation cannot be bypassed; these are 32-bit architecture devices, whilst all recent versions of iOS/iPadOS are designed for 64-bit hardware platforms. The iPad mini1 is obsolete.

You need to consider that compatible Apps for your iPad are increasingly difficult to find - as App developers have dropped support for 32-bit devices and older versions of iOS preceding iOS11/12/13. As older versions of Apps are removed from the Apple App Store, you’ll not be able to (re)download or install them - which may severely limit the usefulness and utility of your iPad. As such, if you want or need to access most current Apps, requiring more recent versions of iOS than your iPad can support, you’ll need to consider replacement of your iPad with a newer or current model.

Of current models, even the entry-level iPad9 has specifications and capabilities that will massively outperform you current iPad - and is compatible with the vast majority of current Apps. Other models are more powerful still.

I hope this information provides clarity as to your available options - and the fundamental limitations of your iPad.

The vast majority of 3rd party apps on AppStore requires a more recent iOS version.

Most likely, your unidentified iPad, still running iOS 9, cannot support a higher iOS version because of hardware (CPU/RAM) incompatibility.
