When I try and manually install my updates, I used my Apple ID and it does not recognize it; however, when I tried to (for example) sign into the Support Community and used my Apple ID it worked. It also works when I download an app. I had this happen before and I took it to the Apple Store and they did a reinstall. I thought it was fixed but it does not appear to be.
Hey there, and welcome to Apple Support Communities BarbRL,
We can certainly understand your concern and can help provide some insight.
We recommend checking to these steps for more information what to do if you are having issues updating your device.
" If your iPhone or iPad won't update
To update your iPhone or iPad, you need a compatible device, an internet connection, and enough storage. It also helps to keep your device connected to a power source.
If you can’t install iOS 16 or iPadOS 16.1 on your iPhone or iPad
You might be unable to update your iPhone or iPad wirelessly — or over the air — for one of these reasons:
If your device doesn't support new software
If you don't see the option to update to new software like iOS 16 or iPadOS 16 when it becomes available, your device might not support the latest release.
If you have a compatible device but your iPhone or iPad won't update, try the steps below.
If there's not enough space to update
If there isn't enough space to download and install an update, the software on your device will try to make space. It will remove only app data that it can download again and doesn't remove or relocate any of your data. If your device still doesn't have enough space, you can use your computer to update your device.
If you can't connect your device to your computer, you can make room for the update by removing content and apps on your device that you don't use. Go to Settings > General > [Device name] Storage.
Learn more about the space your apps and content use.
If the download takes a long time
You need an internet connection to update your device. The time it takes to download the update varies according to the size of the update and your internet speed. You can use your device normally while downloading the update, and your device will notify you when you can install it. To improve the speed of the download, avoid downloading other content and use a Wi-Fi network. "
