[Windows Phone - Familly Premium] No music available on wifi/mobile network.

[Geeeeeeg]

Context
My son is using spotify without any problem on his own account (on the same familly premium plan) with both his computer and his android smartphone.
I'm using spotify on my own account with my Windows 10 computer without any problem.
The problem only appears on my mobile phone.

Plan

Familly Premium account

Country

France

Device

Microsoft Lumia 550 (mobile phone)

Operating System

Windows 10 Mobile

Connection Provider
Sosh (Orange) for mobile network
Free (wifi/cable) for both my computer and my phone.

Issue
When I try to use browse tab it says "sorry, nothing here" and I can't see any of the suggested tracks/playlists.
When I try to use search tab the searching process never ends (it never find anything).
I can still listen to my library synchronized music (offline) and the synchronization works well.
This happens even whenever I'm connected by wifi/mobile network and, of course, I did not activated the application's offline setting.

Spotify doesn't care about it's subscribers and abandoned Support for the Windows 10 mobile platform. The official App no longer allows you to browse. Try running SPOTIMO BETA - it's awesome!
