Objects catching on coincident edges

My game uses tiles to generate a random level, and all tiles have the same edge pattern at connection points. I have confirmed that the models were exported correctly aligned to the origin, and are placed correctly in the unity editor. The tiles have bounceyness on their assigned physics material. When my test object crosses the edge between two tiles it will either ignore the edge, stop as if the edge is a wall, or bounce upwards. The tiles use mesh colliders. Is there any way to fix this problem or merge the geometry of the tiles in the unity editor?

Give the player a PhysicsMaterial with 0 friction, should fix it
