We are using June 2019 Patch 3. We are also heavily using the navigation button by Stefan Walther. In chrome, this extension works perfectly fine. On the other hand, in IE it is not visible. I've done some testing and used the older versions to see if we can roll back and use those but they fail to import into the QMC so I'm assuming those are outdated. I've read similar issues (latest one going back to 2019) but it looks like it just doesn't support IE. I'm wondering if any of you were able to get it to work in IE? Obviously, we could go with the out-of-box Qlik's button but it doesn't have the aesthetics as Stefan's extension provide.
