Hi @marga,
Thank you for reaching out!
We’re sorry for the late reply. With the current COVID-19 situation, we’re short on staff and every request take a bit longer to be handled. ?
Usually, this issue stems from incorrect permissions for the theme fonts directory containing cera.ttf. In that case, your website is not able to open the font file, thus slowing the loading process or displaying an empty square for the missing icons.
Changing the permission settings to let the font file correctly load using your FTP client will probably fix your issue.
