Hi Jelena,
I am aware of some issues that occurred recently as a consequence of major change actions affecting the support infrastructure (related to the simplification of incidence reporting systems, the rollout preparations of the ONE Support Portal etc) - this might have been the reason for some of the "missing" mails. However in general mail notification should work, and sorry if inconveniences have been caused.
Would you mind to open an incidence for one of the specific issues where a mail should be created but apparenly is not? Do not hesitate to contact me directly in case the incidence is not handled properly or no reasonable explanation is given.
Hope that´s ok?
Regards
Bernhard
