Hi BarbaraW​. I can't specifically comment on devices receiving updates that should be paused. Please open a support case to help dig into this.

As for additional "optimizations" anew feature should be launching later this month (all 9 more days of it), called Windows Autopatch Update Readiness. This was announced at Ignite late last week and will add a whole new set up tools to ensure your devices are ready to receive updates and help you troubleshoot and resolve issues with any of them getting updates. Look for more info on this soon (or search up the sessions from Ignite for info as well).
