SNAPSHOT ends in unauthorized access error

When I want to share a chart via SNAPSHOT and open this link in an other browser , I
got an error :

Problem! Unauthorized

Does it show the snapshot? Or is it a popup error after the snapshot loads?

Here : I did a screenshot

It did not show the snapshot, only a popup

I can recreate this error. If I save a snapshot of a dashboard with alerts (and alert annotations - error, ok etc.), then panels with alerts are not loaded. This is a bug in Grafana. We are doing a lot of work on annotations at the moment so we will fix this very soon.

Thanks for reporting this @skirsten
