This is only an unquantified Hunch at this stage, however I’m starting to get the feeling that NextCloud is slowly becoming abandonware. Used to run a self hosted instance of NextCloud, but dropped it after repeated performance issues. Went to a managed instance, but even with only a limited about of files, finding that it’s randomly slow at times. The App keeps kicking me out of a document editing session and lacks many features found in Google’s and Microsoft’s suite.
Started searching for an alternative, but sadly it appears NextCloud is still stated as the most oft recommended solution.
