is there a limit to the number of address? I have >500
There is a limit to the number of addresses per route. Our free plan has max 20 addresses per route, the upgrades have max 100 or 200 per route. There is a public beta test with max 500 per route.

A workaround is to group your addresses in smaller sets, e.g. by city, and create a separate route per set.
