@Dyolf77_WMF: Assuming this task is about the StructuredDiscussions code project, hence adding that project tag so other people who don't know or don't care about team tags can also find this task when searching via projects. Please set appropriate project tags when possible. Thanks!

@Aklapper : Thanks for adding that project.

@Dyolf77_WMF -- if the user is explicitly pinged in the Flow response, do they get a tray and a bell?

@MMiller_WMF Yes, they get a tray and a bell:

Thanks, @Dyolf77 for reporting! I checked on arwiki betalabs for both - when a question is answered on a Mentor discussion page and for questions answered on Help desk. I did not see that Reply with mention will produce two notifications.

That how I tested:

• • user A posts a question to a mentor's Flow-based page or Help desk (also Flow-based)
• user B answers user A (and mentions user A with {{FlowMention|user A}} - user A receives only one notification (an alert).

However, the topic will be added to user A watchlist and all other updates to the topics will trigger notifications.
For example, below the screenshot shows that the first notification (an alert) was with a mention; the second - a notice- was just reply on the topic (the notices will be sent for any update of the topic).

The bottom line - mentioning a user on a topic should not send a double notification - only a mention (it was specifically tested for Echo notifications) . If you notice that it's not the case, I'll look into it again.

Thanks @Etonkovidova for testing this on beta wiki,

@Dyolf77_WMF -- if the user is explicitly pinged in the Flow response, do they get a tray and a bell?

@MMiller_WMF Yes, they get a tray and a bell:

I noticed that the tray is because the topic was closed. So corrections to my comment above:

• You are right @Etonkovidova, mentioning a user on a topic sends only one bell notification;
• Not mentioning a user on a topic sends only one tray notification.

So when a question from a newcomer is sent to the help desk, who will reply to that question have to mention the newcomer to make sure they will receive a bell notification as shown in this message:

Thanks @Dyolf77 for rechecking and clarification.
