Interpretation feature problems

Has anyone else experienced this? 

In a meeting with multiple virtual and in-room attendees and participants, and using the interpretation feature  (English to Spanish).  After a few hours of normal operation, the Main and interpretation audio channel suddenly swapped (so Spanish was hearing English and vice versa) No settings or configurations were changed, it just did it by itself. After about 10-15 minutes it swapped back to normal. This happened multiple times over a 2 day,  all day long meeting
