iPad Air 2 MDM enrollment issues with Apple Configurator

Hello,

I have been experiencing issues with enrolling iPad Air 2 devices into our MDM for the past few weeks. Additionally, after removing these devices, I am unable to add them back using Apple Configurator. They are running the latest available software version for this model, which is 15.8.4.

Could you please let me know if Apple has discontinued support for iPad Air 2 in business solutions or MDM environments?

Thank you in advance for your help.
