We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Let me please inform you, that our forms are mobile friendly and usually look good on different devices. However, there are many factors (i.e., website layout, form layout, used form fields and widgets) that might affect the form appearance, so each case is different.
Note that it is possible to do custom CSS injections including @media injections to style the form for different devices.
If you need any further assistance, please let us know.
