Hello. I have asked about a similar issue previously but it continues to occur on new devices. The issue is with the sixfab not establishing a cellular connection and the cm-logs are shown below. This has happened to me in the past and I was told to use an older version of the OS. I have used multiple of these HATS and used new images of the Lite version recently (yesterday) and I was able to get the device working fine with cellular. I am setting up a new device with the same OS and clean image and this problem occurred again. This also happened last week but the day after I simply retried and it worked again. I would like to have a repeatable solution that ideally does not require I use an old image as it seems it’s possible to have it working with the newer OS. Let me know if you need more information. Thank you
