On an iPad Air, I open the goJS sample. Everything works as expected.
Now when I use a gesture to go the the home screen and then open the Browser with the goJS sample again, I am not able to interact with the diagram.I cannot move nor select nodes. The rest of the website (i.e. not the anvas stuff) still works.
Same behaviour in our Cordova app.
It doesn’t happen for the Kanban board.
It seems to happen if the canvas is larger than the current viewport or quite close to the bottom of the page (probably it has to do with where the touch event ends?)
If I use the Flowchart while the tablet is in portrait mode, it doesn’t happen either.
I can also reproduce it here in landscape, but not in portrait:
I’ve uploaded a 2.2.19a version (not a release) with a potential fix. Could you try it out and tell me if you can still reproduce it? It may also be worth testing in your own app.
