My labels window has collapsed - horizontally, not vertically - and so now I can only see the inbox and starred labels. I have tried all the options listed - I can see the 'Meet' tab, I have tried clicking on the 'hamburger' tab, but this is more for a vertical collapse as opposed to a horizontal collapse. I cant clear this so far.
Does anyone have a clear and simple fix for this frustrating quirk that has suddenly appeared?
