while giving team in ticket comments some users getting notification other not getting

@John Funk ,Thanks for response, tried when added and after 1hr same issue.
the team is not tied to group, its stand alone team with members added directly.
another question that this users should have access to that project with service desk team Role to get the notification. 

I think we have exhausted the help we can give you here. I suggest you open a support ticket with Atlassian so they can delve into it. Please post back here with the resolution, as we would all be interested in the cause.

Hi @Jason Krewson ,Thanks for response,they are getting mail and notyification

directly mentioned (for example, @John Smith),but when mention team not getting .

Sounds good, so that rules that part out.

I would recommend comparing the users that are not getting notifications to the ones that are. Group membership, project role, and project permissions would be a good place to start.

Also make sure they have the "Browse Project" permissions in the project the team is being mentioned in. 

as checked in that project have browse project permission have this
 

So that shows "any logged in user" meaning they would have the browse project for sure as everyone that logs into your Jira site has it. 

@John Funk mentioned some good suggestions, I would recommend checking that next to see.

okay let me give the other screenshot .

We added Neeraja, Isha, and Shrey along with the existing members, but the newly added users are not receiving notifications when @Marketing Science is mentioned in ticket comments. We are unable to identify what configuration the previous employee changed. Please help confirm whether any permission, notification setting, group mapping, or automation rule needs to be updated so the new users also receive notifications.

Hi 

Do the users you add , have the correct permissions?

have this permissions and yes yesterday added them in project with service desk Team role.

HI @Abilash 

As they are in the role or they granted an Agent license to use JSM, via admin.atlassian.com?

Hi @Marc -Devoteam- ,Thanks for response ,yes today we provided the access to project and given service desk team role to them.we have to validate that.
