The issue you are facing
I have the same problem as this user here had last year:

Missing tag function

Nextcloud version: 14.0.3 Operating system and version: Ubuntu 18.04.1 LTS Apache or nginx version: Apache 2.4.29 PHP version: 7.2.10 The issue you are facing: I wanted to categorize my data using tags. But there is no chance to add them, because everything concerning tags is just missing as if the feature was turned off. I tried solving the problem with searching the forum and Google as well as searching for an option in the Admin area. But I didn’t find anything. Maybe I am just missing s…

Unfortunately, there was no answer so I am trying again:

I am not able to add tags to files - there simply is nothing available regarding tags. I can’t search by tags, and in the file detail window there is no way to add tags.

Is this the first time you’ve seen this error? : Yes

Steps to replicate it:

1. Open a file to “Details” view in Browser
2. No option to enter tags
3. No filter option on the left side

Any ideas? This one drives me mad. Without tags, we also can’t use stuff like “File retention” and files access control based on tags.
