Sermon duration not working

I tryed with codemirror and tinymce with the same results.
The reason i haven't updated to joomla 5 its because i'm affraid of breaking some old extension.
But i've been thinking that i must do it

You certainly should do it.
Try it first with a copy (using a backup) of the site, if you're unsure. But the pre-update checker should be quite accurate in which extension potentially could be an issue. And then you can check on those.

I'll do a test with Joomla 4 tomorrow. Maybe I have broken something there.

Thomas,
Upgraded to joomla 5 and it seems its all ok now.
I'll do my best to translate to pt-PT wich is king of diferente than pt-BR

I was able to reproduce it with Joomla 4. It indeed is a bug in SermonSpeaker 6.1.6 which only happens in Joomla 4.

In Joomla 5 it is working fine.

That means I have to raise the minimum requirements for that version and further updates have to be Joomla 5 only. Which isn't a bad thing anyway I think.

Thanks for your testing and notifying me.
