Hello @JohanT98 ,
Thank you for staying on the beta program. We apologize for the inconvenience and appreciate your contribution to the beta program. Please note that although a master reset does provided a clean slate, it is very unlikely it can help with network related issues. We recommend you wait until next software update to see if connectivity improves.

"I want beta management to know so they have an idea of how many people are leaving do to connectivity issues."
The more appropriate way of reporting issues is NOT HERE, but in the Beta Feedback tab of the Members app.
