Everything works as expected, unless the value submitted for 'address' contains a has symbol (#). In that case, the hash symbol isn't escaped. Let's say the value "#3-276 Second Ave." is submitted as the address. The URL in the email ends up being something like: https://www.mydomain.com/redirectToForm?address=#3-276%20Second%20Ave.
Am I missing something, or does Hubspot need to fix this?
This is still a bug and it's very annoying. It randomly breaks form submissions - not good for our users' experiences! Please reproduce and/or reach out to me for help, and fix ASAP. We pay a lot for Hubspot and I reported this a year ago.
