[Helios Prime sentinel not scanning.]

Tip that has worked for me, try equipping a non-maxed Investigator mod on him. I tried it with one almost maxed out, and now he scans about 80% of the time on the starchart, where-as before he would never scan.

[Helios (Prime) often won't commence scanning]

Same, still having the same issues. The last patch introduced the bug.

Ok, so i'm not crazy and this thing is buged. Funny, i pulled my never used helios prime just for it to scan acolytes and it gets broken.

Yeah it's not just you. It's super weird though, it works fine on PoE scanning ghouls but is completely broken and not working in starchart missions.

[Synthesis and Codex Scanners are not highlighting scannable enemies and objects]

Yeah they still haven't fixed it. Affects both the scanners and Helios' auto-scan ability.

[Am I using the Scanner Wrong?]

The patch somehow introduced a bug that a lot of people are having issues with.

My Helios Prime doesn't scan and the scanners don't work correctly manually either.

[Scanners not showing colours on targets]

Same, they aren't working correctly for me.

Had the exact same thing going on, my Helios Prime isn't scanning things anymore. I've tried the same things you did.

 

On PC, it's been going on since the patch yesterday.
