Version 3.7.0 is now released in the App Store. It might take an hour or two to see it everywhere though.
As I wrote above, this is a gradual release where the automatic update will be done in the timespan of a week. You can update right away through the product page in the App Store: https://apps.apple.com/us/app/stage-traxx-3/id1448493366
The updated documentation is also available now: https://stagetraxx.com/user-guide/
I have created a new Frequently Asked Questions page in the user guide as most users did not find the FAQ area in the forum. So any new FAQs will be published there from now on.
