FYI - I read through that M500 thread again and found what I was trying to remember for seeing if the SU-9 has the latest firmware - I cannot vouch for this, but one poster noticed that the “new” firmware, with the fix, did not have 2020 in the “
2020 SMSL” part under the firmware numbers (is just “SMSL”). I had purchased my SU-9 in Feb 2022 and my firmware screen does not have the 2020 in it, so it seems reasonable that this information is correct.
Edit - here is a link to the post, which includes a screen shot:
