After some initial hic-ups, my SG has been working perfectly and has undoubtedly increased my sales. 3 days ago the items disappeared and the gallery just shows 'loading store window'. I've seen it on other sellers' listings too, so thought it was just a glitch but it's been a happening for a while now.

Does anybody what's up with it?

PS I've already generated a new token and it had absolutely no effect

Mine was the same way last night but it's ok now...
