Lock iOS13 location button?

[ColinO]

Apologies if this is not the correct forum, I managed our primary school iPads with Mosyle, and have, on the whole been quite happy with it. I often hold back iOS updates until everything has well settled, but have noticed an issue. On iOS 12 and below, I can, using restrictions, lock the Location toggle-button so it is on, and greyed out so it is locked. However, now that I am using some iPads on iOS 13, the location toggle is available and can be turned off, which I don't want. Am I missing something, or is it an iOS13 thing? Thanks.
