Loss of Standard Outbound/Exit Link results

HI, we migrated to Launch at the end of April.  At this time, we have realised that our standard reporting of exit links stopped appearing.  My colleague did the migration and i've checked on the Launch property - the checked box for tracking outbound links is still there.  has anyone else experienced this?  i've asked our IT team if anything happened to the website around that time, but while i wait i wanted to reach out and ask, if there was anything from an Adobe perspective because my manager believes the timing is too much of a concidence.
