I used the companion app on all my Zwift sessions, its a great tool for supporting the main Zwift app. One usability suggestion, would it be possible to either separate the -/+ buttons on the map sizing or design them where its easy to zoom in and out? The feature is a great one to help navigate the maps or to locate group leaders. However, i find the map sizing buttons small and fickle, with varying degrees of success.
Also, i may be wrong, but i don’t think there is a gradient display on the companion, again this could be useful.
