Hi,
I recently notice an issue (not sure if it always been like this) where I use the List Gift API with last modified date specified and expect to get gift last changed since 12hrs ago. This is to update my data warehouse of gift information. However, I added gift custom field onto a gift and then ran the api, and found out the gift I added custom field to did not show up. I also tried a few times after that after 10-15 minutes. Then when I go into database view and look at the gift record's property, it does not show that the gift have been updated by me recently.
I'm going to test this again but wanted to report this and see if others are seeing the same thing.
