Notes not showing in webbrowser

[GHBLoos]

Please make a clear and concise description of what the bug is.

On my desktop PC: When clicking on the notes icon on the top menu, no notes are displayed. Except for the top menu, the screen is empty. On my laptop: I was working on notes, and I closed the laptop (hibernated it). When I just opened my laptop from hibernation Notes is still working. Last Note was not yet saved. When I open a second browser window and open Notes, it is also an empty screen. Also after saving the note, the other browser sessies are still showing empty screens. When leaving the Notes screen on the open browser sessie and navigation to Dashboard, and then back to Notes, Notes is also empty. So now on all browsers sessions (two computers, multiple brands of browsers), Notes is not showing when clicking the icon. When on Dashboard: if I click on new note in the notes section, the new note is not appearing on my screen, but it does on my android device, so it is created.

• Android app works fine.
• On nextcloud dashboard, the notes are shown normal

I am not sure if there was an update of notes last night.

Steps to reproduce

Hard to reproduce, since I'm still having the problem

1. click on the top menu notes icon
2. nothing appears
3. I can't install a previous version of notes. That might give more info. Might be related to a new update Might be related to hibernating a computer while working on an note (and note was not yet saved).

Expected behaviour

Showing the normal screen with notes

Actual behaviour

Empty screen (just the background with the nexcloud top menu)

(The error below might be because I turned on my laptop.)

I have exactly the same behaviour as described, without hibernating a computer, but after updating notes. Tried on Firefox, Opera and Edge on win10.

Notes app version: 4.9.1 Nextcloud version: 27.1.3

[GHBLoos]

After upgrading from 27.1.3 to NC 27.1.5 the problem seems solved.
