The beta software doesn't work with APAC devices. That's stated in the announcement and production FW for APAC devices lags that for ROW devices - a few weeks to a month or two.
Please note, the beta updates released on these forums are not suitable for APAC region devices.
Thanks for the reply, i'll return it next time when i'm on Taiwan. Wanted to solve battery drain issue with the new software (drains in 4 days instead of 20 as promised)
Update is available but I'm unable to install the Spotify app as it states that device is not compatible (despite being 5.1 apac model).
Is it working for you?
