Hello @HotelGranduca ,
If the button looks and functions as expected, then that will confirm it was something specific to the button in your original sendout, and you can perform a follow-up email / correction email to your contacts. With that in mind, it'd also indicate that you may be too many copies-of-copies deep, and there's now junk coding that needs clearing from the template. You'd either want to start copying from a Master Template for cleaner coding, or from a more original source if you can find it. Otherwise, you may need to start replacing certain blocks from within future copies.
If the Live "test" you send yourself still doesn't work / ends up with the same issue, please let us know so we can see what other troubleshooting options may be available for addressing this.
