Good morning,
We have noticed that on some of our older apps the data tab button under tree view on the left hand side has gone. I have has a search on the forum and all I could find was to switch this slider on:

However it won't let me do this I get the following message:

Where can I find the switch it is saying I need to turn on first and will it effect anything? The reason it's so important is so we can find the SharePoint pages they are connected to.
Any help greatly appreciated 🙂
Thanks,
Edd
