When using a bluetooth keyboard with Android there are some keys that do not work (even though they work locally on Android). So far we've seen these keys:
* å, ä, ö
Tested with Firefox 68 and Chrome 78.
I've retested now and it does work in Firefox (and Firefox Preview), but not Chrome. It's also specific to SwiftKey. I've reported the issue to them.
Closing this as we consider this a SwiftKey bug and we cannot track it.
