Not sure it was a great idea to always show that modal, it took me a while to figure out that I can close it, I thought it's an ios app...
Yeah, we will change the styles to make it more obvious that it's modal. Sorry for the confusion.
2. QR codes are scary (at least for most in the American market; other countries could be different). Instead of a QR code, show a random string the user has to input. We are all used to inputting random numbers/string when doing 2-factor.
I'm not against using QR codes. I just didn't realize that I could close the modal window, and thought that I had to jump through hoops to try out Sketch.
Given the amount of crap that can be found on the internet, I have a very low threshold for losing interest.
A better approach would have been to remind me later than I can scan a QR code to access the page on my mobile device.
I understand your point though. I suppose they can improve it.
You could:
1) Have the QR code contain a real URL, with the Expo ID appended as a querystring.
3) On the server, redirect to the appropriate app-store depending on the browser used to open the URL, or open sketch if installed.
3) Have Expo interpret the querystring to open the correct "sketch".
