Hello,
Apologies for the inconvenience.
This usually happens when the font size set in the addon is too large for smaller screens such as iPhones. To resolve this, please adjust the mobile typography settings for the addon.
You can reduce the font size specifically for mobile devices in the addon’s Typography settings. Setting a smaller font size for the mobile breakpoint should keep the header properly aligned and prevent it from going out of position.
If the issue persists after adjusting the mobile font size, please let us know and we will be happy to assist further.
Best regards.
