We have upgraded a number of AP to V20.2.1 (Beta1 or Beta2). We have some SM in the field which were not upgraded since the SM was off (owner on vacation or has been turned off for non-payment).
Now we are having issues when they are coming back and being rejected since they don’t support multigrant.
The CBRS log in the AP looks like this
04/30/2021 : 15:34:19 UTC : CBSD is already registered with SAS
04/30/2021 : 15:34:19 UTC : Disabling multi grant mode since radio is not capable
04/30/2021 : 15:34:19 UTC : Requested operation parameters cause too much interference in the CBRS spectrum.
04/30/2021 : 15:34:19 UTC : SAS Error : Rejected due to PAL incumbent
04/30/2021 : 15:34:19 UTC :  Too much interference caused by the device for other users, hence grant rejected
04/30/2021 : 15:36:19 UTC : Failed to send Grant request [Err: CBSD_SUCCESS] after timeout
tried to edit the SM for power etc but that has not worked.
We have 23 other SM on this same AP in various EIRP powers working fine. We have other AP with V126.96.36.199 SM and they are working fine in Widegrant status
Since the SM can’t log in, it seems our only option is a truck roll?
