Hi,

AllowTileSizing property is not working properly in the following scenario.

Step 1:

Set AllowTileSizing as Individual and try to resize the tile. It will work fine

Step 2:

Now change it to Synchronized and try to resize the tile. It will work fine.

Step 3:

Now change it back to Indidual and try to resize the tile. It will not resize the tile.

After setting Synchronized once, if i change back to Individual resizing a tile is not working.

Attaching a sample for your reference.
