Ipad cases
Will an iPad 10.5 case also fit an iPad Air 3?
iPad Air 3, iPadOS 14
Question marked as
Yes.
The 2019, 10.5 inch screen iPad Air 3 is directly based on the 2017, 10.5 inch screen iPad Pro.
Try to find as case that is NOT too tight fitting.
There have been long standing touch screen issues with both the 10.5 inch screen iPad Pro and 10.5 inch screen iPad Air 3 due to cases the held these iPads too tightly in their cases.
Also, some FaceTime connection issue, as well.
Maybe get a looser fitting folio case that has looser side/corner protection to minimise unnecessary flexing of the iPad in the protective case.
Just giving you a FYI.
Best of Luck to You!
