I would like to have some advice / clarification on one of the rules in D&D 5e from some more experienced players or DMs. I read somewhere that an advantage on attack rolls cancels out a disadvantage, so the roll is made normally. What happens though when there are two effects that grant an advantage and only one effect that provides disadvantage?

e.g. Kobold rogue / valor bard class with 2 attacks: in the surprise round the kobold rogue is hidden granting him advantage on attack rolls, it is broad daylight so he has disadvantage. He also has a party member within 5' of his target, which grants him advantage due to Pack Tactics. Does the kobold rogue make both attack rolls with advantage?

I believe that this section of the Basic Rules may be helpful here! Here's the relevant quote for ease:

If circumstances cause a roll to have both advantage and disadvantage, you are considered to have neither of them, and you roll one d20. This is true even if multiple circumstances impose disadvantage and only one grants advantage or vice versa. In such a situation, you have neither advantage nor disadvantage.
