Following up on @ahblake’s comment – I've implemented entities from repeats in Central but Collect (v2025.3.3) doesn't seem to support it. The entities from repeat Central update thread responses make it seem Collect 2025.4 beta 2 does support forms with entities from repeats.
Is there an update for the launch of Collect 2025.4? Would really love to have this for my new project but will default to manual manipulation into a .csv if need to!
