I followed the instructions from "How do I find the most recent date from a connected object?", but the dates I wind up with (after converting to a number in the child object, then going to the parent object and using Max to find the new one, then converting back from number to date) are WAY off. If I use "hours" as a date format, I get numbers about 50,000 years in the future. If I use "days" as the date format, all the resulting dates are from 1970, when they should be in Spring 2021.
Hi - I have used that approach in the past - but I have a working example where I just use a formula in the child object like this:
And then use a Max field against this - seems to work as expected.
