The warning symbol appeared this morning, but there is no other information when I touch on the symbol.

What does it show when you click on see recent updates? Anything showing in your apps list?

No nothing has failed to update, it's clear.

Normally when you get a warning symbol like that it means either one or some other one has failed to update.

Everything has updated so it must be a bug. Tried everything even clearing the cache but it still remains.
