Thanks for your message! And nice to know that the problem has been solved!
I'll take a moment to answer your questions.
You can adjust the size of the text by going to the settings of your button. Under the "Style-tab" you can open the Label container and there you can adjust the font size.
You can enlarge the button itself through our Custom CSS Editor, but this is a premium feature and I see in our system that you have a free plan. Have you maybe considered going to Premium? If this is the case, I can help you increase the button size.
Let me know if you have any other questions.
