I started implementing my software using maps api v3. Unfortunatelly i found out that v3 API has some serious issues which draws me back from bying a bussiness licence.
I was facing this issue in only mobile browsers. The drag/pan was smooth in desktop browsers but when it came to mobile there was lag when user dragged the map. I spent like 3 hours on this and finally realized that a missing meta tag was the reason.
Basically if you do not include this meta tag
the problem comes. I feel incredibly stupid for realizing this after 3 hours or not adding the meta tag in the first place. But anyways if someone else is also making this mistake I hope I saved some of your time.
