Edit activity intervals - doesn’t work

The ability to edit interval types on Garmin connect whether on mobile app or website is broken for me.

If you click edit on an activity, see more data, intervals, highlight the ones you want to change, click on change, choose the new interval type, you can see on screen that it changes it but as soon as you hit save it goes back to what it was before.

Could someone possibly try this on an activity and see if it works? Just in case somehow it’s just me.

I posted about this but genuinely can’t find it now sorry.
