SGPro does not see PHD2 starting

I never had a problem with this in SGPro 2, but recently paid the money for 3 and now when I start my sequence, SGPro starts PHD2. I can see PHD2 select a star and start guiding automatically, but SGPro continues to say “waiting for PHD2 to start”. But it has started. I almost wish I had not upgraded. The only way I got around it was to turn off PHD2 in SGPro and start it manually, but then I loose dithering. Really frustrating. Anyone else have a solution to this?
