Massive issues following Firmware Upgrade
Have had a 5 unit M9 Plus Mesh for ~5 months.
Worked seamlessly until latest Firmware update.
Following download and update, all slave units periodically dropped in and out of connectivity (red flashing light on deco unit).
Performed hard reset (manual) on main Deco, which then caused app to stop recognising prior setup network. Deleted and reinstalled app, same problem.
So to test, set up second network. Main Deco plus one Slave. This worked for 15 minutes, before same problem.
I now have two networks in my house: original one (which I am unable to reach as can't get past setup page through app) and secondary one which has the same problem as the original.
All after the firmware update.
Need advice on this! Have others had issues after Firmware update?
Cheers
