Samsung calendar long alerts don't work properly

[Members_aH6xOT9]

I went from A52 to S25+ and I'm seeing the following problem:

Samsung Calendar offers 3 different types of event alerts. The "light" and "average" functions work properly, but the "strong/long" function does not work and not only does a screen similar to that of the alarm clock not appear, but the popup doesn't appear either

Edit: the "medium" alert can launch the full screen alert routine. But the sound and the duration is very small, so if i am in another room i could miss It. That the reason why i used the "strong" alert type, which doesn't work now

Yes, but it doesn't fire the usual full screen alert i used to have with previous samsung (maybe it's a UI 7 problem)

Same issue on S22 since for about one and a half month. Customer service couldn't help.

Yes, having this issue with the Strong setting on S25Ultra,

Medium fires but its too low in sound & strength to even get notice and for too short time.
