I've been trying for a few days now to get the test mode up & running on Chrome, Safari or Firefox (on MacOS) -- but these sessions keep running out of time without showing anything (progress bar up, but nothing else).
Run mode instead seems to work just fine, but I'd reeeeally like to get back on track with test mode; after all, instant reload is one of the Flutter USP...
Just adding this post here to alert the FF team that this issue persists, as it seems that a lagging test mode has been an issue for quite a few users in the past months.
I'm hoping the issue can eventually be pinpointed and solved... (@team Flutterflow).
