You can change the visibility of the upload component or the submit button so that it’s only visible if the Logged In Users > Uploaded Files is less than 51.
When I select logged in user there is no uploaded files option. The options I have are email, password, username, full name, created date and updated date. Please help
Create a collection called “Uploaded files”. In this collection, you can keep the default “Name” property and then add a new relationship property to the user collection. “A User can have multiple uploads. A Upload belongs to a single user”.
Now in your User collection. There will be a new property in there called “Uploaded files”.
Now you can use the visibility rule that Ben recommended.
