XC90 Pure Electric Question

Just purchased a used 2022 XC90 recharge and am having issues with engaging/maintaining the pure electric drive. My presets are set to default to pure electric. First morning commute with full charge, it never engaged using hybrid the whole drive. Drive home after work it engaged and worked the whole time. 2nd morning with full charge it initially engaged, but somewhere along the drive stopped going to hybrid despite near full charge. What am I doing wrong? I drove highway speeds of 60-65 with no hard acceleration. My commute is only 6.5 miles so should have plenty of charge for both drives.
