Ipad not pulling latest os

If your iPad is currently running, or cannot be updated beyond iOS 10.3.3/4, then have an iPad4.

Update support for iPad4 ended September 2017. The final iOS releases for this model were iOS 10.3.3 (WiFi Only models) and iOS 10.3.4 (WiFi & Cellular). iPad4 cannot be updated to any later major version of iOS as it lacks the minimum hardware requirements needed to run more recent versions.

Many App Developers have also dropped support for older devices and iOS versions preceding iOS11/12/13 - and have withdrawn older versions of their Apps from the Apple App Store. Withdrawal of Apps supporting older models of iPad is making their utility and usefulness significantly more limited. Once compatible versions Apps are withdrawn, you’ll not be able (re)download or (re)install them.

If Apps that you need to use now have higher minimum iOS-version requirements, your only option is to replace your iPad with newer model. Of current models, even the entry-level iPad7 supports current iPadOS 13.x (and the forthcoming iPadOS14) and has hardware specifications and features that will vastly outperform your old iPad4. Other models provide a corresponding step-up in performance and features.

I hope this information is helpful - if only in clearly outlining both the limitations of your current iPad and current options.

As said, if you have an iPad 4 it cannot update beyond iOS 10.3.3. Its simply too old to support anything newer.

if you don't have an ipad air 2 like your signature suggest but an ipad 4generation

then that would explain the ios higher than 10.3.3 is not supported.
