Hi. Thanks a lot. I would need to do a rollup summary field, not for a sum, but for a max date (last project date for example). What would be different in the flow then please? I cannot make it work...

Hi, thanks for you video. It really helped but when I try to use it for deleting contact, total numberofcontacts on account object is now 0 instead of going from 3 to 2 (as I only deleted on contact). Can you help?
