I concur with this report. I use the webclient a lot with my short cuts. I have added two images. The light one has the shortcuts in the previous version of the webclient and the dark one has the shortcuts in the new version of the web client.As you can see, several of the shortcuts are missing in the new version.
When I compare the two views I noted that the missing shortcuts are all related to tags.
I use Chromium as my webbrowser: Versie 79.0.3945.79 (Officiële build) Built on Ubuntu , running on Ubuntu 18.04 (64-bits).
Hope this helps, tracking this bug.
