please reread this important notice to all beta testers
To avoid further confusion, please unset Test mode if you have not done so already.
That way you will avoid stumbling over insufficiently tested or non-working alpha versions.
As @mervinio explained, sometimes you may specifically be asked by the developers to set Test mode and OTA to re-test a feature that you reported broken or not working correctly in a beta version.
Please hold on a little more, a new beta will arrive and be announced soon.
