Going commercial makes sense.
But I have to say the way you guys do it is not optimal.
First you strip down the free version. In a previous conversation it was mentioned that the current version / toolset will remain free and that the pro version will get the more high end tools.
PDF export and master pages are now Pro rendering Gravit for my students pointless.
I currently get a lot of error messages because of used up cloud space - gravit does not even allow me to see how much I have used up.
The strength of Gravit I see is in the online version. In terms of performance, snapping ability, drawing tools, etc it lacks behind even apps like Inkscape since years. Roughly for 3 years I am preaching to improve snapping and the pen tool.
Look Sketch is cheaper and Affinity Designer is even cheaper and single purchases!
As a desktop app Gravit cannot currently compete - and I am a little concerned that you rushed the Pro switch.
