does discord affect the traffic balance?
Nop. I don’t think so. 
If you think it affects please let me know.
i was comparing my balance last month and this month but it seems when I used discord there’s an abnormal used of my traffic balance? can you double check it if it’s the issue? or is there anything else that affects it?
No problem. However did you check ‘Status -> Access Log’ to see details of traffic usage?
