Digital Pin14 not working on Nano 33 IoT

I'm using all of the Digital pins (0-21) on the Nano 33 IoT so I don't have the option of just excluding any pins.

I initially reported that D17 was not latching but I tried a new Nano 33 IoT and this one works fine.

However, on both boards D14 (A0) (DACO) isn't working as a digital input or output. I see it also provides DAC functionality. Has anyone had difficult with this pin?

It seems odd I would have the same failure on two boards.

Yes I saw this as well. I was able to move to D15 and use that as a digital out. I have investigated it any further.

I've had problems on 14 for sure. I don't try to use it as a result.

I have 2 Nano 33 IOT boards and pin 14, aka A0, work as digital inputs and outputs on both
