Did you find a solution for this ? , I too used to get this error sometimes when my app is already installed in development . I had to uninstall the development version to finally install the production one

No, I didn’t find any solution.

I tried uninstalling the dev version but it made no difference.

In my case, the solution was to check the App Versions in the marketplace. From there I can see the installation attempts and read the error. It turns out I hadn’t included the documentation link.
