After hours and hours of trial and error I found an hint.Â
My saved settings spread over one thousand lines, but finally I found that just removing this oneÂ
remindersmultipopup=1
the repeat reminder feature starts working again.Â
The first reminder fires up and so the "repeated" ones, and all of the play the Pipe sound I chose (CG internal).Â
Now, if I enable the "Display multiple events in popup window", i.e. the one I manually removed from my config, then the first reminder fires up, and strangely enough it no longer plays the Pipe sound but a kind of a smartphone default notification tone, and there are no more "repeated" reminder (or maybe they are there but without any sound? it's just an hypothesis I could not verify anyway.Â
Dominique, come back to me soon...Â
