Hint settings not working - "Server error; please try again later"

I have tried to change the hint settings for one of my trees - I was able to delete all existing hints but when trying to choose a different set of hints I get - Server error; please try again later.

I am asked as usual to sign in to FamilySearch but no hints then appear and when I return to Hint Settings they have all been cleared.

I’ve tried a few different times today but still getting the same error

Everything OK now server seems to be back on line again hints setting saved and hints appearing
