If it says Solstice of Heroes and is an empty screen which you can only dismiss, it is a known issue and is being looked into by Bungie. As the SoH event has already passed some time ago, there is no gift to receive, just an issue with the UI.
Also, the forum is the way to report issues as you just did.

It does indeed say Solstice of Heroes. I guess i'll exercise patience then. Thank you for the info
