Flux notifications disappeared and can't see missed calls logs

Hi , this is my first post here. Thank you so much in advance for reading the following request. 

My organization started using Teams as a Phone service a few weeks ago.

Few days ago, we stopped recieving Flux notifications for missed calls (only reactions, messages or calendar organization).

Now, when a new caller times out without an answer, we have no logs of this call via Calls > History and we can't even see a new red pin to tell us that someone called and missed the call.

Can you please suggest a solution ?


Thank you in advance,

Best regards
