Did you connect the router to the internet before trying to run the software update?
In case you cannot connect the app to RyngDyng anymore, please follow the emergency procedures described here: Emergency procedures
Please note that the button to update the pre-release software is always displayed to our “advanced users”. This is a setting in our database. Some of our users want to get the pre-release versions, so that’s why we enabled this button. You should press it only when you know there is a new pre-release version and you want to get it.
In case you need more individual support to fix the problem, please write an email to ticket@archery-analytics.com.
