I already filed a bug report but want to make sure it is not my computer.
I bought a new Laptop (Macbook 2016) and my webapp (and every other bubble webapp that I know of) is extremely slow when I use Safari. Just look here:
It took over 20 seconds (the screen recorder I use only lets me grab 15 seconds.) for the popup to open. The same happens with the popups on my site. With Chrome and Firefox everything works fine.
I have macOS Sierra 10.12.1 and Safari 10.0.1
Can somebody else with a Macbook doublecheck (also please write down your MacOs Version and Safari Version)
