Fontsize in GUI very small on UHD display and not scaling with Gnome Tweak Tool

I’m using the latest Nextloud Client 2.3.3 with Fedora 27 on a HP Spectre X360 with UHD display. The fontsize of Nextcloud GUI is very small and it can’t scaled with the Gnome Tweak Tool.
Can you please implement compatibility with GNOME Tweak Tool, so the fonts of Nextcloud are scaling like all the other apps?

Can you please open a bug report on github.com/nextcloud/client/issues?

OK, opened a new bug report: Fontsize in GUI very small on UHD display and not scaling with Gnome Tweak Tool #205
