Mentions on the app

while managing some tasks using the app, as I type any updates, I can’t mention anyone specifically. Either I mention “everyone on board” or anyone at all. I need to mention someone already tagged on that tag.
What can I do?
Can anybody help me with this issue?

Thank you so much!!

Hi @Mariane, welcome to the community!

I’m wondering if you wouldn’t mind expanding a bit more on which app you’re using at this time? Is it one you created yourself?

Feel free to DM me with specifics too, if you’d prefer.
