Hi @Tuna, it should be a bug in our code. The camera is supposed to keep recording even off WiFi connection. We should have one test case for this before we do every official firmware release. I don’t know when the issue was introduced.
I will have our engineering team investigate on this and provide a fix as necessary. Thanks and there is no need to contact our support team (it will come to us anyhow 
). Thanks for reporting this issue!
update: a bug was filed on 2/1. We will work on a fix for it.
