I just did my cert in the PNW this month - there was plenty of time spent on breathing, but also emphasis that doing compressions is the important part. Interestingly, the instructor thought this change was mostly due to amateurs being far less comfortable with giving breaths and being likely to refrain from CPR altogether if they thought it was necessary to do the breathing.

FWIW I have done it by video during covid and in a live class before and after, and I did find it much more engaging and memorable in person. It was surprising to realize that, but simply having the additional sense memories seems to have made a big difference to retaining the information.
