Anything affecting access to essential network endpoint — ad-blockers (including those built into browsers like Brave), strict Firewall settings, network proxies, custom DNS servers — can affect Express functionality. If you are using these, please make sure that the network endpoints listed on https://helpx.adobe.com/enterprise/kb/network-endpoints.html are allowed.
I had the same problem as Mary5FFC (share and download button appear but no text). This issue was also meant I could not search for any assets in the left-hand pane.
In my case it was related to my network setup. I have a custom DNS server (PiHole) set on my ethernet adapter. Therefore, I tried switching over to using the WiFi, which has no custom DNS server set, and this solved the issue straight away.
