Disable prompt to "install the Web Companion App"

I was wondering the same since its constantly popping up even though its installed.

That sounds like a technical issue that should be fixed. Have you reported this to M-Files Support?

No I haven't yet Joonas Linkola Im gathering all customers who are experiencing this issue.

It's not currently possible to disable this prompt so I recorded a new feature request (ID 169459) for it. If you already have Web Companion installed and are still seeing this prompt, there may be an issue with your firewall blocking some connections. Please see Web Companion: Troubleshooting FAQ for more information.
