Display problem of IGN maps on map overlays
In Progress
Hello Locus map team,
I have this problem for a long time, but only now I make this report.
I have French IGN maps, online and some offline areas.
I have very often problem when I want to display it on map overlays. To see the screencopy of the error. This hapen in both IGN maps online and offline.
I found a turnaround : I select IGN map as base map, use it a little bit, select offline LoMap as base map and then IGN map works on map overlays
Note:
- I always use offline LoMaps. Very few online maps.
- Offline IGN maps are downloaded at zoom level 16 only.

The same problem 
Hello Rafael,
I'm not sure why exactly this issue happens on your device. Anyway in the next app version, app will try to load the overlay maps twice. There is probably a small issue in initializing of WMTS-based online maps too early. So give a try to the next 4.33.0.10 Beta version (this friday) or just wait a few weeks till new app version will be published.

Hello,
complicated problem for me to fix > nothing like this happens on my device. Anyway, one more update will be in todays (later) Beta. App will retried up to three times to initialize map so hope, it will help. If not, I'll have to add some log messages on correct places and you will try this special version that should tells us more. Thanks!

Hello Menion,
With last beta version : 4.33.0.11 and after a clear of temporary data : not solved.
First I would like to resume my use case.
- Map base : Offline LoMap (France Nord), Hike´bike and sometimes Elevate themes.
- I use IGN maps with "Map overlays" mainly.
1) Offline carte IGN, of small area, downloaded at zoom level 16 only (I do not download all zoom level).
2) Online Cartes IGN
3) Online Plan IGN V2
4) Online Photographies IGN.
I start with base map at zoom level 16.
On map overlay none of these 4 IGN maps worked . A window warning with "mapf30.c@xxxxxxx is not ready. Code: 12591".
"Satellite Hybrid asamm" does not work, until I change the zoom level.
I change base map to Online Cartes IGN. After the 1-2s of "Initializing" pop up windows, it works.
On map overlay, Offline carte IGN and Online Cartes IGN worked. Online Plan IGN V2 and Online Photographies IGN does not worked.
I change base map to Online plan IGN V2. After the 1-2s of "Initializing" pop up windows, it works.
On map overlay, the 4 IGN maps worked. "Satellite Hybrid asamm" does not work, until I change the zoom level.
Ready to test a special version.
Thanks
