I have a quick question. Why exclamation mark doesn't work in UTM parameters.
I will give you an example - this url which is generated by external tool doesn't work and redirect to home page:
https://www.example_site.com/xx/xx/xxx?utm_source=facebook&utm_medium=cpc&utm_term=XX&utm_campaign=Test_Test_Test&utm_id=xx1!12345678
But when i manually delete ! mark from utm_id (last part) it starts working:
https://www.example_site.com/xx/xx/xxx?utm_source=facebook&utm_medium=cpc&utm_term=XX&utm_campaign=Test_Test_Test&utm_id=xx112345678
utm_id is generated automatically so I cannot change it other way then manually all the time.
How could I solve this problem and why this is happening?
