keynote keeps going blank during presentation
My keynote keeps going blank during presentation. I use the iphone as a clicker. I have to keep pressing esc and return to play mode but after a few slides, the same problem persists.
Everything works fine during testing the day before.
I am wondering what the cause is:
- file size too big?
- copying some slides from previous keynote presentation?
- mac/iphone going to sleep mode during the talk?
Appreciate advice on this! Thanks.
