    Prepopulation doesn't work with comma and "(" ")" for a string field event if I encode those as %2C ; %28 ; %29 . Is it only me or there is a known limitaion?

    Hi Vitaliy,

    While URL encoding characters like commas (%2C) and parentheses (%28, %29) should work, they can occasionally cause issues when prepopulating string fields, especially if the field or form logic parses them differently. We recommend simplifying values when possible or using alternative methods like hidden fields with calculation values. 

    Can you send me the link to your form so I can take a look at it, and see what's happening? You can easily find your form's URL in Form Builder. Let me show you how:

    1. In Form Builder, in the orange navigation bar at the top of the page, click on Publish.
    2. In the Quick Share tab, click on Copy Link in the Share With Link section.
