Just want to give a shout out to @joeworkman!
I was working with a site last week and having some major issues with a few of the stacks that I deem as critical. For some reason, there was an issue on mobile devices that could only be fixed by removing those stacks. I was seriously bummed.
As I entered my second day of troubleshooting, an update for the Post Office stack came out with a release note about fixing an issue with conflicting js. Sure enough, that did the trick and I was back to work!
So way to go, Joe, for keeping up to date with all of your stacks, even those that I bought years ago and still use today!
