Ok, so this is what happens.
When you change the country to one that doesn't allow for channel 149 and up, the Almond+ doesn't auto select the correct lower channel.
At the moment you have to select the correct channel in the web UI and it'll work, i.e. in the case of Finland, you need to select 36-48 rather than 149-161 as the EU doesn't allow for the higher channels.
Hopefully this makes sense and we'll work on getting this fixed in a future firmware update as it's clearly confusing and annoying.
