my TX16S came with v2.7.1 from factory.
I seemed to have used EdgeTX Buddy to 'upgrade' to v2.11.4 (the latest)
now nothing works and the user interface is so wildly different than all the help videos online. nightmare.
Where / How can I get v2.7.1 back ??/
it is not offered in the pull down menu in EdgeTX Buddy :(
