Prepped last night for a longer ride today. Bike shifted fine. App stated 90% battery for both batteries. Today, started my ride and the front derailleur wouldn't shift, Rode the about 60 miles in the small chainring. When I got home, I removed the CR2032 button battery. Voltage measured .87 volts. Installed a new battery and all is well. I recommend replacing the "Lynkcell" brand CR2032 battery with high quality Batteries. Who would think that with only 500 miles on the EDSTX kit, the button battery would be bad.
