UC Browser AdGuard Kill Injection

I rarely use my data plan, but today I did: enabled Adguard, turned data on. Almost immediately Adguard became disabled. This was logged:
UC Browser
injections.adguard.com:443
66.209.11.33:80
https tunnel

Looks like UC is actively fighting us. This has never happened using wifi.
Have a Gfive Logic X1, unrooted with 4.2.2 & Arm v7. No other firewall or interfering software.

My first shot in the dark guess would be the browser is using some sort of "data compression" (aka data saver in UC Browser), but I'm not sure if it'd cause this or not (I'll try to test this browser when I get some time). The devs will probably need logs for this one.

True that I've compression enabled for data on the browser, but I've used it previously with Adguard enabled & had no problem. This was a direct injection attack against Adguard specifically.

injections.adguard.com is a virtual domain which is used to serve cosmetic rules to the web pages. Adguard should've intercepted that request.

However, "https tunnel" means that AG failed to decrypt connection for some reason. I wonder why it happens on cellular data only.

Could you please collect Adguard's log for me?

I understand. Been unable to reproduce it so far - I'm still receiving the same UC 'injection' (only on data) but it's not shutting AG down.
I'll try a few more times - anything that can disable any adblocker or firewall is worth investigating. Thanks for getting back to me.
