I have an issue where in one umbrella situation ==> I am running Chrome Browser and I have two tabs open, one to App #1 and one to App #2, I am seeing buttons from App #1 in App #2.
This is pretty much a crazy failure on the part of the App Bridge. I would highly recommend cleaning house of this kind of bug, as it makes Shopify and us developers look totally bush league. Not to mention, what if this is in production and Apps start sharing buttons?
I assume I only see this as a developer and that in reality, this bug is not really a thing... but it is a thing, and I see other developer complaining about it. So it is not just me.
