OpenWrt 23.05.4 - Service Release

Thank you. I thought after enabling advanced settings i would see SNAPSHOT builds listed as a firmware option under "Attended Sysupgrade" as an option. What am i missing? I might download the snapshot build and flash that way, but if i can do it via the attended sysupgrade route, i'd prefer to figure that out. Any ideas? Screenshot doesn't show it in the drop down, but the only option in the drop down of "select firmware version" is the one that is [installed].

Adding screenshot as a sanity check to make sure there really isn't another option. Especially since at the top it says "new firmware available".

I decided to try something else. I tried
auc -c -b 23.05 -B 23.05-SNAPSHOT
from terminal, then i it starts to do stuff, then eventually errors out with
Error: Received incorrect version r24016-f791ec1f6d (requested r24014-76a0c2932c)
Bad message (77)

which my research hints could be an error with the caching of the build server? Anyways, i'll just wait it out for tonight and try again later. I posted all the above in case it helps someone.

I'm editing my post, as i think i found the information i was looking for regarding using auc or other means to upgrade to 23.05-SNAPSHOT from current 23.05.4
