I don't think it has to do with connectivity because it happens to be 100% of the time when tanking. Glad that this is being looked at because it definitely wasn't fixed after the patch where it said it was being addressed.
There's a bug report on this a few weeks back: https://answers.ea.com/t5/Bug-Reports/Tank-Damage-Direction-Indicator-Showing-Incorrectly/m-p/7548423
@SterlingARCH3RI also reported it in January but accepted as solved when the patch notes said it was going to be addressed: https://answers.ea.com/t5/Bug-Reports/Invisible-or-Wrongly-represented-enemy-tank-shells/m-p/7400202#M10300
But it was obviously not fixed.
