I see that you’re using an older version of Polaris which includes an older version of App Bridge. As of App Bridge v0.8.0 the Flash actions were deprecated in favour of Toast actions. With recent changes to how Feature Detection works, Flash actions no longer will work. A potential fix for this issue you’re experiencing is to upgrade to a new version of Polaris. Here’s a link to the Toast documentation and working with App Bridge using Polaris documentation.
I’m currently using Polaris 3.1.1 and its not using the Flash action (I used Polaris Toast component and I guess the Polaris embeded app bridge powered Toast component)
so you reckon upgrade to the latest will solve the problem?
Do I need to migration my current Polaris Toast component to App bridge version?
