Worldmap not presented

We are using Interviewer.App version 22.06.7 (build 30204) with Maps support.

The problem we are facing is that the Worldmap (default map) is not presented in the tablet:

Open Street Map has not problems:

Dear aguinada,

The default World map is used only to demonstrate the functionality in offline mode and therefore has really modest resolution. Because of that you can see just a blue colored background without details at this zoom level.
I would suggest you to upload custom map of this territory or use online one like on the second screenshot.

Thank you for your clarification vfedoseev
