Slow loading presentation from desktop app in Mac

I just purchased a new MacBook Pro running Big Sur and loading a desktop version of a presentation is so slow I abandon and go to the browser version. Am I missing something? I’ve had different problems on a pc, so I switched to a mac, and the desktop app is still a non-starter :frowning:

Hi @Dean_Morbeck, does your Mac have the new M1 Chip?
