tylerm Hi Tyler, thank you for reporting this issue!
Indeed, in the previous version the max size of an image was set to 56px. since version 2.1.0 we have changed that to 100px, but I see we have forgotten to update the max-size property in the CSS of the image in the button itself.
As a temporarely fix, are you able to add the following CSS to your webpage:
.buttonizer img {
max-width: unset !important;
}
This should fix your issue for now! In an update next week we'll remove that CSS line! 🙂
