In my experience the Snap ! editor on iPad is unstable, both with Safari and e.g. Chrome. Sometimes it suddenly freezes. If you try to save the current state of a project (“Save”) a window will pop up: “Saving project to the cloud …”, but nothing actually happens. Many other menu options won’t even react to being touched. Function blocks can not be opened for editing. Script pic and some other functions will usually still be active. Sometimes, if you wait for an hour or so, the editor apparently unfreezes - the thing to do then is save the project and close the window, or even the entire browser.
Snap ! was built in JavaScript, which has the advantage that it is available on many platforms. IPad is a very popular platform, in my view it would help if the Snap ! development team could make Snap ! and iOS (?) more compatible than they are now.
Thanks in advance!
