Can recreate using two CPXs, one running this TX demo:
https://github.com/adafruit/Adafruit_CircuitPython_CircuitPlayground/blob/main/examples/circuitplayground_ir_transmit.py
and one running this RX demo:
https://github.com/adafruit/Adafruit_CircuitPython_CircuitPlayground/blob/main/examples/circuitplayground_ir_receive.py

CircuitPython 5.3.1 with library bundle adafruit-circuitpython-bundle-5.x-mpy-20200901.zip.

This is what shows up on the RX side:

Adafruit CircuitPython 5.3.1 on 2020-07-13; Adafruit CircuitPlayground Express with samd21g18

Is there any more info on this issue? I'm trying to send some sony codes with this library and am puzzling over why it does not work but it could be a lot of things... [added later] this turned out to be related to trail functionality, see number 3 in #40

I'd be curious what happens if a long sequence is sent there, e.g. something like [0x22] * 12
