I know it was mentioned in the 24th July Home App update but it's only in the past couple of weeks that I've noticed a massive improvement. I initially had my Pro connected via ethernet but relocated it to another room and added a mini, connecting both via WiFi. I then had frequent issues with device discovery and my devices suddenly forgetting who they are at multiple times in the day but never got around to raising a ticket. All sorted now it seems.
