This release resolved an issue introduced by an update to the Echo on 2/10/2016. It also attempts to resolve at least some of the UPNP port conflicts by opening the port shared. Other apps that do the same can have the port open and each will get a copy of all requests to the port. It may still interfere with other processes that don't open the port shared, but it's an improvement. With this change, we've now started the discovery process at plugin start time and it will run indefinitely. You can still stop/start discovery yourself using the menu items and/or actions.
Is it possible for the Sonos plugin to open port 1900 in a shared manner?
