You can also try this: delete your element, and redo it from scratch with new class names, but under Safari, not Chrome. Webflow designer in Safari. This is one way to make some things work in Safari with Flex…
edit: actually that setting seems to fix it for Safari
BTW I found that you can log into Webflow on iPad pro with this browser: iCab Mobile (Web Browser) on the App Store Set the appropriate user agent. Don’t expect much, it’s for the fun :)… Editor works quite well though.
