Do you feel comfortable when people address you informally?

Comfort in using "you" depends on the context, company culture, and personal preferences. In a professional environment, it is important to respect established communication norms. If the team commonly uses "you" and it does not cause discomfort, then such a style can be used. Otherwise, it is better to stick to a more formal address until it is clear that "you" is acceptable.

Personally, I am open to informal communication if it promotes more productive and friendly interaction.
