Thumb row Issues
I am having some trouble with the the keys in the thumb cluster on my wireless corne. I have isolated the issue to the nice!nano controller, by swapping the controllers and re flashing the firmware. The issue started on the left thumb cluster, and migrated to the right when I swapped controllers. The keys are unresponsive, and the largest thumb key (which when held sends a Shift modifier) seems to be held down.
I have tested the continuity between the P0.11 and P1.11, P1.13 and P1.15 pins on the board and didn't see that they had continuity. I reflowed the solder on those pins and can't see that there are any shorts between pins there.

It sounds like you're experiencing a hardware issue with the thumb cluster on your Corne Wireless keyboard. Since you've already swapped the nice!nano controllers and reflashed the firmware, we can focus on the hardware connections.
Here are a few steps to further diagnose and potentially resolve the issue:
1. Check the Diodes: Each switch in the thumb cluster has a diode. Ensure that the diodes are correctly oriented and soldered properly. A faulty diode can cause keys to behave unexpectedly.
2. Inspect the Solder Joints: Double-check the solder joints for the pins you mentioned (P0.11, P1.11, P1.13, and P1.15). Sometimes, a joint may look good but still not make a proper connection. Reflowing the solder again might help.
3. Test the Switches: If you have spare switches, try replacing the switches in the thumb cluster to rule out any faulty switches.
4. Continuity Testing: Since you mentioned testing continuity, ensure that you are checking the correct pins on the nice!nano and the PCB. Refer to the schematic for your keyboard to confirm the pin mappings.
5. Check for Shorts: Use a multimeter to check for any shorts between the pins and nearby traces. Even if you don't see visible shorts, there could still be an issue.
6. Inspect the PCB: Look for any physical damage or cracks on the PCB around the thumb cluster area.
If you've gone through these steps and the issue persists, it may be worth reaching out for further assistance or considering replacing the nice!nano if it's determined to be faulty. Let me know if you need more help!
Some additional info: The keyboard has been working fine for about a year, this issue just suddenly came on. There are no changes that happened that might have caused this. I didn't mess with the solder, re-flashing the firmware, etc.
