I can confirm it with Nextcloud 25 and Notes app 4.7.1 (debain 11, nginx, php 8.2, mysql)
I tested both rich text and editor mode

Edit: But I have to be fast enough, otherwise autosave triggers first

Suggestion:
It appears to be this section of code. Why not add an commit call here instead of warning the user ?

notes/src/App.vue

Lines 339 to 343 in 6dca9d7

	onClose(event) {
	if (!this.notes.every(note => !note.unsaved)) {
	event.preventDefault()
	return this.t('notes', 'There are unsaved notes. Leaving the page will discard all changes!')
	}

This is a browser limitation as it is not guaranteed that any requests performed during the before unload event are handled. This event is explicitly only for asking for confirmation. As far as I'm aware there is no way we can ensure that the file would be saved before navigating away except blocking with this dialog.

why did it worked on nc25?

[apg1980]

furthermore if i just stay on an note it appears while changing the nc site

What do you mean with "it worked" ?

For me (on nc25 and nc26) it behaves as followed:

• If I edit a note wait for some seconds and then change to another app the note is saved and no warning appears
• If I edit a note and try to click fast enough on another app the warning appears

In other words (like the code in my comment showed #987 (comment) ):
If you leave the app faster than the background asyncronous saving of the note is finished the warning appears to prevent data loss.
The latency of automatically saving a note should depend on the servers performance and you network connectivity, If I am not mislead.

i did never get an popup on latest nc25 with the latest notes app on realease date of nc26 before upgrading to nc26. this behaviour is new, the environment (server nginx etc did not changed)

[juliusknorr]

Do you use the plain markdown or the rich editing view? For the plain markdown the logic shouldn't have changed at all from 25.

[apg1980]

same behaviour on both methods.
next thin i can see, notes are not getting saved as expected before.
you can see the star beneth the note, latest changes are not saved after minutes.
i lost some important notes today, after leaving the typed notes.
