I also just bought version 2. I'm now traveling with my Surface Pro, and the app is unusable. I already have my display set to 175% at the OS level, and that doesn't seem to have affected Affinity. The fonts in Affinity modals look like they are 7 point font.
This shouldn't be a nice to have. Nobody should have to vote up accessibility. Check your company values, and if you care about people on smaller screens or with eye issues, you just make it work. You don't wait for someone to vote for it. Your values make it a high priority. Someone has to care how many people are likely to be affected by this.
Thanks.
