Apple integration question

I was super pumped to hear about the Runna + Apple Watch integration update. I ran my first easy run through the Apple Watch fitness app after merging Runna workouts with Apple Watch. Usually when I run using the Runna app on my Apple Watch, I get alerts that I’ve completed a mile and pace updates after each mile during easy runs. However, I did not get any updates throughout my run using the Runna workout through the native Apple Watch fitness app. Is there any way to turn these on? Will I still get pace alerts and run splits on interval/tempo runs if I start the Runna workout through the native Apple Watch fitness app? I rely heavily on those during my interval/tempo workouts to stay on pace. I’ve looked through settings in both Runna and Apple fitness, and I didn’t see anything that was blatantly obvious to change to get these alerts to come through again.
