I need users of the website to be able to update what they have previously submitted. For example, they give a brief bio of themselves but may later want to edit it in some way. Or it could just be a change of address.
It seems an elementary feature, but I can't see how to do it anywhere.
I would like to know this as well - as well as how to update the community page URL if they update their username.
Good news! I found this: https://support.wix.com/en/article/corvid-tutorial-creating-a-form-for-editing-data-in-a-database-collection
The video doesn't help, but the instructions do. The only remaining problem is how to access a particular item to be updated rather than the entire database. I guess that can be done with filters.
