Notifications gone blank

(Shouldn’t there be a bugs/issue forum for stuff like this?)

Just one notification from nearly 4-hrs ago - everything else gone.

(I should add this is in the new, advanced view.)

Back again this morning, thanks.

Correction: they’ve gone again.

All past notifications have disappeared again, but now it seems every time I cause a notification, it deletes the one preceding it, leaving the most-recent one.

They appear to be back again, thanks.
