Thanks for this addon.

When using it, I can't see the "master/" folder. All I see in arm64-v8a is:
Nexus/
Matrix/
Omega/
Leia/

Is it the expected behavior ?

No, You should see the master branch while navigating nightlies; I believe the issue is related to a bad mirror host.
Please install my beta repo  and install the lasted version v.1.3.5.
If you still encounter problems, try opening the plugins settings, click "Default" and "Ok".

Any further issues will require a log. THX
