[Qgis-user] Automatically force reload layer from source (geojson)

[Richard Duivenvoorde]

Hi Olivier,

Does F5 (refresh, from menu 'View/Refresh') not work?

I thought that when I had an (live changing) online geojson source, (and
added as url), I could easily 'reload' fresh data via F5

Not working for you?

Regards,

Richard Duivenvoorde
