I've followed this tutorial in order to get started in development for Teams.
The 'Hello World'-style app works fine within the desktop environment, but it doesn't show up in the mobile app. Are there specific limits for developing mobile apps in Teams? I've found this thread, but its quite dated and doesn't even mention the mobile version, so hopefully things have changed quite a bit?
Not being able to use an app that you've developed yourself in mobile form seems like a massive oversight. Especially for me since the app needs to function on both desktop and mobile. Therefore developing for desktop alone won't be viable in the long run.
I think it's an area which is specialist and needs the right people for guidance and an authoritative answer. Here in the Tech Community in the main Teams forum, 99% is administration and voice as opposed to development (there is a bit, but it's not what is needed - somewhere development focused). I have been pushing with the community for a dedicated developer forum here on the TC as there is only Teams and AMA at present. Much of the Microsoft Teams dev community is over on GitHub.
