Thanks for your questions about our app on iOS. After checking with some other techs and developers we were able to confirm that the "save to reading list" option is not functioning properly. There is currently no way to access the contents of that reading list. My apologies for any inconvenience that this has caused and my developers have been made aware of the issue.
After doing some research I could not find a reason why the Handoff feature wouldn't work - so long as you were using the Covenant Eyes browser app on two different iOS devices. Also, at this time, no extensions will work within the Covenant Eyes browsers on iOS devices.
Thanks again for your question Kaleb and I hope this helps. Have a great rest of your day.
