If the issue was fixed quickly and the full interview still happened, you usually do not need to escalate it.

Technical problems are common. What matters is whether they materially reduced your interview or affected the evaluation.

If three minutes were lost but the complete case and fit section still happened, a separate email is probably unnecessary.

If meaningful content was skipped or time was lost, send recruiting a short factual note.

If the full interview still happened, I wouldn't make it a thing.

I'd email only if the tech issue actually cut content.
