By default, Backendless has always used the WGS84 coordinate system.
In the US cluster this parameter was used implicitly, unlike the European cluster e.g.
On Monday, maintenance work was announced, which also affected the optimization of work with the databases.
But the main point is: your data remains unchanged, they are the same as before maintenance.
So, if you created/imported them in that or other type, that type you’ll see in web-console.
The optimization affected on how spatial data are stored. As a result from now you will receive more precise results for all spatial functions, and their behavior depends on the type of SRS (spatial reference system). At this point we support two: WGS84 and Cartesian, but may add more in a future.
