Hey @DesignerDiana I use both Chrome (latest version) & Safari to use Webflow as those browsers are supported for the Webflow app.
When you experience any lag within the Webflow app is it from any of the following?
- Slower Internet Connection
- Intermittent Internet Connection
- Small amount of RAM (2gb or less)
I’ve never had any issues with Webflow on PC or Mac, sometimes on Chromebooks with very little RAM it ran a little slower than I’m used to but was still working fine.
Please let me know 
also if you’re ever experiencing any issues be sure to email support@webflow.com with as much information as possible, the team really appreciates it.
Thank you,
Waldo
