Device didn't check in for 6+ months needs a restore.

Hi everyone,

I work in the education sector and we have iPads that weren't used since we closed down schools in March. I noticed that some of them, if it has not seen a wifi connection for more than 6 months there's no way it'll do a check in unless I do a restore manually.

Unfortunately, we might have a good number of iPads that are in this state.

Has anyone gone through the same ordeal?

Thanks
