We do not receive Emails when we tag each other on a confluence page anymore

we are using @ to mention people in content of a confluence page but No Email is being sent to ppl tagged on a Confluence Page anymore. When we tag newly created users they can get an Email once but after that no Email is being sent to them. This feature was working fine before and we could mention different people several times on a page and every time they could receive an Email with the comment.

We use this feature a lot and it is really difficult for our client to follow up newly added comments now.

Is this problem related to apps, APIs, or ecosystem? If so how? If not, maybe you would get a faster and better answer via our customer support mechanisms.
