Android Companion App Takes LONG Time to Connect/Pair to PC on Ethernet

I run Zwift on a PC connected to Ethernet. Each time I start the Zwift application on the PC and start the companion app on my Android smartphone it takes several minutes (3 to 5 usually, sometimes 10!) for the companion app to connect/pair up to the PC application. It always EVENTUALLY pairs without any intervention on my part, but it takes a LONG time.

Does anyone else have this issue?

Why would this be? Does anyone know a workaround? Is there a fix coming?
