Unable to fetch Download URL

[MC874]

Introduction

I'm trying to download Minecraft Beta version using latest version of MCLauncher (3.0 Update). Its apparently shows : Unable to fetch download URL for version. For beta versions, please make sure your account is subscribed to the Minecraft beta programme in the Xbox Insider Hub App

Problematic

I've already signed into Beta program and never do unsubscribe, it's been a year staying in Beta program, so it's should be safe. Turns out, the MCLauncher still can't find the URL for Minecraft Beta version. It works fine while download Minecraft Official Releases

I'm having the same issue, been trying to fix it for a day or two now, extremely frustrating because minecraft preview doesn't pop up in insiders hub

Beta versions have been unavailable for quite some time. Sadly there is nothing we can do about it.

Is the beta versions can still be accessed somehow? It is kinda weird that they pulls every beta versions from MStore @dktapps
