Maps in MapView/MapTrackView loading slowly or not at all

I have been tinkering with MapView and MapTrackView over the past couple of days trying to build a custom navigation app for SDK 3.2.0+ devices. Most recently, I have been able to overlay a series of markers and a polyline on a MapTrackView representing a route I took running the other day. My overlay looks fine but for some reason, the rest of the data is either not loading or taking a very long time to load!

On the simulator, I see only my overlay against a white background even though my route runs through the centre of a large city (Montreal).
On my device, I am presented with a "Map loading" screen that can take up to 10 minutes to resolve, and even after that I can only see major streets with very little detail.

Is there something going on with your map service this weekend?

Which devices/target devices? In the sim map data is pulled off the web, but on real devices the map data is on the device.

What happens with the mapsample from the SDK?

With MapTrackView, the view itself will draw the track if you have GPS on, and there are other things that will differ between the sim and real device.

The same thing happens with the map sample (in fact, it becomes unresponsive and I cannot back out of the app in the sim). I have tried with the fenix5plus, fenix6pro, and fenix7x. I have also tried running the app on a physical Fenix 6 pro.

These screenshots are from the sample:

And I am running the latest SDK version (4.1.2).

Update: it seems like this problem only happens when I am connected to my home Wi-Fi. Even though it is a fast connection and I am not having any other issues, there is a networking problem somewhere along the way that is preventing the sim/my watch from connecting to your map service.

What happens if you run the sample on a real device? As I've said the sim works differently with maps than on real devices.

Try this one of mine on a real device:

Here's what I see in the sim with a f5+:

The maps start showing within seconds for me.

Could it be your pc/mac has access to the maps blocked? I think it uses openstreemaps.org
