Describe the bug
During first start of the Notes app on Android (installed via F-Droid) I am prompted to select the nextcloud profile, then whether I accept the access to nextcloud from nextcloud notes and then I get an error. If I close the app and open it again, I end up with the same.
To Reproduce Steps to reproduce the behavior:
- Open app
- Click 'Select account'
- Select account and press OK
- Allow Nextcloud Notes to access Nextcloud when being prompted
- Then the error pops up
Expected behavior
Connect to Nextcloud and display notes

Additional info
Hostname and SAN DNS Names in the x509 cert do not match. This is intended though currently, and I would expect a popup to prompt if I trust the cert.
Not sure if that's of any relevance here.
If I do not choose from an existing account and select to create a new one, I can successfully log into the nextcloud instance (I am asked whether to trust the certificate). However, I end up in a kind of browser-like view of Nextcloud. I can select the Notes app from the Apps in the header, but I can also do everything else..
I don't believe that is intended? I would expect to see only my notes and a text field to edit the notes in the Notes app. But not the complete Nextcloud browser experience.
Below image is the Notes App.
Also, when I then close the Notes app and open it again, the just created account does not appear in the list (maybe because it would be a duplicate of an already existing account; which, when I select that, leads to above error!?).

To summarize: You can not log in with the main Nextcloud Android app successfully?
Having set up a working Nextcloud Android app is mandatory for using the Notes Android app given it uses the Single Sign On feature to pass through network requests.
Please ensure that the Nextcloud Android app works properly before signing in to the Notes Android app and, if necessary, open an issue in the repository of the Nextcloud Android app.
Sorry, but everything else is a follow-up error and can not be fixed on this side.
I did not open the Nextcloud App before using the Notes App. The Nextcloud App always worked.
- I opened Nextcloud App (works as usual, no need to sign in again)
- Open Notes -> Works
So, I always have to open Nextcloud App before opening Notes? Another error description could be helpful : )

No, of course not 😄 So, i misunderstood the quoted part and assumed you are not able to use the Nextcloud app at all - reopening.
Well, after starting Nextcloud App once, it now seems to work.
I restarted my phone and only opened the Notes App. Still works.
I removed the account in Notes App (Select account icon top right, choose handle accounts, then delete the account), reopened again, chose account, granted access (like initially) and it still works (unlike initially).
I removed account in Notes App and this time rebooted phone afterwards. Opened only Notes App after reboot and selected account, granted access and ... still works!
So, I'm having a hard time reproducing the error after https://github.com/nextcloud/notes-android/issues/1849#issuecomment-1651224283
