IGN maps "unknown error"

Hello,

I'm using locus for years but still have an issue with french ign maps downloaded from the store. Despite the latest version of locus and a valid subscription I have the "unknown error" message on the maps.

This issue has been kind of ongoing for years now. Multiple devices, app reinstalls, new maps downloads ... It's always working for a while and then it stops. Since it's taking forever to redownload the maps I would like to find a proper solution.

Thanks
