Sorry to hear you are having problems. I converted to v4 a while ago, whenever available. Had no problems with it to my two Aurrender streamers.
Have you deleted it and reinstalled?
Aurender Conductor V4 issues
About 10 days to 2 weeks ago my V4 app started giving me problems. I have an ipad pro with Ios 16.4.2 I think. I don’t know if the iOs update started it or if it’s something else. I’ve been in contact with Aurender support a couple times and they had some issues on their end. I just can't seem to get the glitches, freeze up to stop. Anyone else? It worked great for a long time and then it just started acting up. I am thinking of going back to V3 for the time being.
