Window tint questions

I just had my windows tinted about 20 minutes ago and it looks great! The shops rule of thumb is to wait 2-3 days before rolling down the windows. Apparently this time frame is either reduced or increased based on the weather. We are currently going through a heat wave right now in Philly, do you think I will be fine putting the widows down after 24 hours?

Also, the windows slide down a bit when opening the door, will this have any effects on the tint?

Thanks!
