Thanks for your question and I'm sorry to hear about your issue. That sounds frustrating. For the sake of clarity does this happen on any and every device on your network? Including devices that Covenant Eyes can't be installed on? I ask because you mentioned Chromecast and Roku - which we aren't able to be installed on. I will say that older versions of Android™ would indeed conflict with apps like Netflix and you couldn't watch Netflix while Covenant Eyes was installed and functioning properly. However, if your Android has an operating system of 12 or newer then Netflix should be usable while Covenant Eyes® is installed.
It is also very interesting that this issue seems to only happen while on wifi and not when using data. Traditionally, with older operating systems this issue would have been consistent across both wifi and data. Do you know who your internet service provider is and whether or not their wifi and/or router comes with any advanced protection defaulted on. If so that would explain why the issue happens on wifi only.
