I'm testing the new Android app, and the exposure controls are working nicely. In the past, I wasn't able to get the exposure compensation to be anything other than -2. Thanks for the update!
If I could add a request, though. When I make changes to the exposure, it would be nice to have those remain in effect, even after quitting and restarting the app. For example, I'm noticing that the ISO always reverts to 400, and the EV reverts to -2. As I said, I can at least change these, but if I'm doing a battery swap, that's one more thing for me to check and update.
