Does travel mode Walking have restriction on distance?

[GKmieliauskas]

When trying to solve route with travel mode "Walking" sometimes I get error message: "Distance between stops is too large to solve using the walking travel mode". The same routing service from web doesn't throw such error message. Is it native application library restriction? I can't say exactly but restriction distance could be about 50 km.

Yes, this is a limitation in the ArcGIS Runtime. When using walking mode, the total extent of all stops must be less than 50 miles. This limit exists because walking travel mode performs a non-hierarchical solve, which can be computationally intensive. Therefore, the code restricts the extent to reduce the load. We allow this on the server/pro version because they would be running on desktop/server machines with more resources, unlike the ArcGIS Runtime, which may operate on devices with fewer resources, such as phones.
