Bad localisation

[Jeff9891]

Hello,

Very often, the app do not locate me in the right place.
It is stuck at a place I was earlier, and won't update my localisation even after I clicked the map logo then "My position".

A less important side bug is that I can't connect CityZen to my OSM accound (authentification server is impossible to reach). Maybe both bugs are related ?

Smartphone (please complete the following information):

• Device: Sony Xperia XZ1 Compact
• OS: Android 9.0 Pie
• Browser : Firefox 65.0.1
• Version : Android 9.0 Pie
