Hey Kristof, I posted a similar question here which has the code blocks on https://www.wix.com/velo/forum/coding-with-velo/updating-repeater-items-not-always-working?postId=6207fdc70b8d6d0017ec8045&origin=notification
Reason for posting here as well as the above was probably quite a lot of info for someone to consume so wanted to simplify the ask.
Any help would be amazing, thank you
