Hi @elliotmr , @mikebp
The updated AT&T firmware with this fix still needs to be certified. What is needed is for the modem firmware version to be updated to 02.20.01.00 or newer. But unfortunately, the PTCRB, AT&T and T-Mobile versions are still lagging as can be seen here https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-latest-release/. Please reach out to your distributor or Sierra Wireless contact to keep track of certification progress. Thanks.
