iPad cannot sign in to iCloud; iOS 11 required, Apple ID limit.

I don't think there is any solution for your iPad problem – other than to replace that obsolete iPad (4th generation) with a new or much newer iPad.

The iPad (4th generation), first released fourteen years ago in October 2012, is a thoroughly obsolete iPad, with a 32-bit processor, which originally ran iOS 6 and cannot update past iOS 10. Apple long ago got rid of 32-bit iPhone and iPad processors in favor of 64-bit ones. Even if you could connect to the App Store, you wouldn't find much of anything there that could run on such an old device. App developers raise their requirements all the time, and even people with devices for which the end of the line is iOS 12, iOS/iPadOS 15, or iOS/iPadOS 16 run into the problem of their devices being too old to run the apps they want.

Apple has raised the minimum requirements for iCloud – and iCloud no longer supports anything earlier than iOS 12, even for very basic functions like Backup and Restore.

System requirements for iCloud - Apple Support

There is a key security certificate that will be expiring at the end of January 2027. Apple released patches to handle this all the way back as far as iOS 12, but no further. So come the end of next January, it's likely that Messages, and FaceTime, and who knows what else, will break on that old iPad.

You won't be able to use your iPad 4 with iCloud:

System requirements for iCloud - Apple Support

“iCloud is supported on the following OS versions or later: iOS 12 on iPhone 5s, iPad (5th generation), iPad Pro, or iPad mini 2; watchOS 5 on an Apple Watch; macOS Mojave 10.14 on a Mac; tvOS 12 on an Apple TV (4th generation); or visionOS 1 on an Apple Vision Pro. Certain features may have different requirements which are listed below.”

You may be able to use your iPad for things that do not involve iCloud but keep in mid that it is quite an old model now and you may find other aspects have limitations such as web pages not working properly.

Hello Apple Support,

By the way, this is a user-to-user forum. You are not talking to Apple Support.

I also receive another message saying: “This iPad has been used to create too many new Apple IDs. Contact Apple Support to request another Apple ID to use with this iPad.”

Maybe a real error … maybe a side effect of your iPad (4th generation) being so old that it can no longer properly communicate with Apple's servers. Sometimes if an operation fails in an unusual way – or a way that developers were not anticipating – you might get a generic error message or a misleading error message.

Oh, and you mention a message saying too many free accounts have been activated, and which is discussed in the support article: If you see “The maximum number of free accounts have been activated” - Apple Support

I don't see that that is relevant here. Creating a new account for the device won't get around its iCloud system requirements issue. You even say that you want to use your existing account, not create a new one.
