Does anyone know if we have various version of SCA bundle - 2019, 2020, 2021, 2022, etc can we uninstalled the previous ones?

Yes, be carful to dont delete the one used on your site.

Any implication of removing the older bundles as I dont think they can be reinstalled back?.

Yes, but i don't see any advantage removing it

Ok. Thank you. It's just being so slow to loading all the version if we need to update the domain touchpoints.

That's weird. I have every SCA SSP from the last 11 years and the list isn't slow for me (it's just really long). How long does it take to load?

It never end up loaded and just stop. I was in the domain record touch point section though. I end up did it from SSP.
