Hi OP, I have noticed what I believe is a bug in v0.12 and wanted to highlight it to you. I have been monitoring the connections from various apps since many days now and have noticed at times that the Network Log of some apps shows incorrect domains under a particular IP address. This happens randomly and not with a particular app. It's a pretty lengthy one and I will try to explain the issue as clearly as possible
I have taken few screenshots for your reference. In both the screenshots, you will see that under the IP address, there is a group of domains listed with only one of them related to the actual app.
In the first screenshot, you will see that the highlighted domains (xx.market.xiaomi.com) are no way related to the app for which the connection is being monitored ("Saavn" which is a music streaming app). The domains are actually from an in-built "Themes" app on my Xiaomi phone. I can say this because I have also monitored the "Themes" app and see these same domains from that app too. This is also seen in the first screenshot. However, you will observe that one of the domains from this group is actually related to the app (c.saavncdn.com).
The same is true for the other apps. In the second screenshot, you will see that the domains listed for the Truecaller app (xxx.deviantart.net) are no way related to the Truecaller app. However, in this case, I do not have the Deviantart app installed on my phone. Even in this case, you will see that one of the domains from the group actually belongs to Truecaller (images1.truecaller.com). At another instance, I monitored the Truecaller app and again saw some other domains which are no way related to Truecaller (as seen in the same screenshot).
I have monitored some other apps too and observed the same behaviour with them. Just to be sure, I have disabled NP and used another firewall app (Netguard) and did not see these other domains from these apps in it's log. Let me know if you need more information. Thanks!
