I was going through a routine check on the mobile version of the sites I oversee - which I hadn't done in a while - and noticed that there was a YouTube embed (or might be Flash) issue playing while the latest version of WPTouch was on.
At first I thought it was an issue with my Galaxy tab, so I spent 30min. on it until I had the bright idea of turning of the mobile version of WPTouch, and it worked! To make sure, I tested again.
You know when embeds are on your post/page you get a little green arrow to tap on to activate the embed? Instead of making the YouTube video appear, it was all white and made the tab super extra slow. It eventually crashes.
So at the moment I've gone back to the previous version of WPTouch, but I thought I would let everyone know.
