iPad Won't Update to 12.4

My iPad mini 4 seems to be stuck at iOS 12.2. The update to 12.4 aways says Update Requested, Estimating Time Remaining…

I’ve tried various kinds of reboots and resets on the device and with my router, but no luck. An iPhone updated with no problem.

Has anyone else run into this?

Have you tried a tethered update by iTunes or just an OTA update? The former doesn’t require as much free RAM.

Thanks! The tethered option worked. Don’t think I have ever used that before…
