Sorry, I was at work and couldn't reply immediately.
I closed all other apps and restarted. I also have way more than 2 gigs available. The problem is still occurring. I haven't tried to reinstall the app.
As of today, I am also having this issue on my iPad (not on my iPhone). Besides being faster, the graphics are bouncier than before. I don't like it and find it very jarring.
@Vee, is your iphone and ipad on the same ios and candy app version?
It appears to be all the levels, although I too find it very uncomfortable so I have not played much since this problem started. I reinstalled but the problem is still there.
It sounds like it could be an issue in the update. As hopefully its not a test. When I hear back, I will let you know but in the meantime, please keep checking the appstore to see if any updates appear
