While trying to create an app with a stack navigator (for an auth flow) and a tab navigator (for the main content), I was receiving an error during live preview saying something to the effect that the tab navigator was missing or undefined. To work around this, I purged the tab navigator. I’m now seeing an odd behavior on my Welcome screen. If I remove or add a navigation action for one button, it also removes or restores a navigation action for another button, respectively.
I’m done for tonight, but will try to add the tab navigator back in tomorrow.
