Intervals.icu not pushing planned workouts to Garmin Connect App

I’ve followed previous recommended steps to address the issue, including removing access permissions in intervals.icu, and in Garmin, then reconnect but doesn’t solve the problem.

Initially it happened a few weeks back on a random day, but now it’s missing my whole week of planned workouts that have been on the system for a few days. I’d also tried to download the .fit file and upload this manually into Garmin which threw it’s own error…

Is there not a feature to allow an API push of the planned workouts?
