I'm working on a new W10 UWP app, and ran into a small issue.
I'm generating tiles with a separate Tile service - it creates secondary tiles, and updates them when required (and also updates the primary tile).
However, for some reason, even though the Wide and Medium templates are used, the sizes the tile offers when right-clicked are just "Small", and "Medium".
I found no reference on how to enable Wide and Large tile options. Does anyone know?
