My Alerts are gone, "no recent alert"

when logging into the forums today, it showed 9 alerts. When I went to see them, they disappeared, and no matter what I do, there's just a message about 'no recent alerts'.

Is there a timer for how long an alert stays in your profile? I've used the feature to tag and get back to interesting posts, where I wait for other users' answers.

 

If you open that dropdown, and then hover away again, sometimes the content is just cleared.

You can find it again by hovering alterts and pressing the "Show all" button on the lower left of the panel that pops up.

 

Thank you for the suggestion, @Baste , but no, the only alert there for me is your reply in this thread. I did find "Watched threads" though, with full history still there - so I did find all the info I wanted.

 

Are you saying that the list on https://forum.unity.com/account/alerts is empty?

 

Well, not empty, there's two alerts there now, your two replies in this thread. The rest (older alerts) are gone, looks to have expired and been removed automatically, even if I haven't viewed them.
