I just set up my M9 Deco Plus 3 pack from Costco V2 and I'm learning a lot but right now using my Samsung Galaxy S9 Plus I noticed when connected to the network it does not switch to the closest and better signal deco unit in my two-story 4,000 ft² house with two units downstairs and one unit upstairs I moved my phone right next to any of the other two and it still doesn't switch the mesh option is switched on within the app and I'm confused any help and advice greatly appreciate it
