iOS setting Lovelace to default (Solved)

I upgraded to 0.84.2 and had lost my frontend on my desktop pc so I selected dev-info and selected set lovelace to default which worked great but it did not work on my iOS beta app 1.5.0
As soon as I selected dev-info the screen went blank.
So I can’t set my iOS device to lovelace default.

Any help please.

Edit: Just done a reboot of HA and I can see dev-info.
