The phone and chat support from Eufy isn’t very good at anything technical. You get a higher level support by sending an email. My interaction with the Customer Support Manager, Angela has always been via email with an associated ticket #90819924 for the issue.
Per her email of May 5, they are working on this issue and plan a firmware upgrade to fix within a 2-3 months. Of course, the issue has been known for around 3 months already, but they have only acknowledged it in the last 2 months. That’s when myself and several other users escalated the issue. We sent them detailed test data describing the issue and showed that it effects most of their security product line.
