Like most people I have a storage folder with many categories and then sub storage folders under each one.

For one of my folders (call it Storage A Folder) I have 17 sub categories when you expand it.

Today there is 16.

One folder has disappeared.

It has not been deleted. If I manually search the recipients in that folder I can see all the emails that would ordinarily be in that folder.

So it seems that it is hidden somehow.

I have done everything that Google has suggested across the internet and cannot find a way to re display that folder from being hidden.

Would love help
