HI, I upgraded to webform 6.3 and the same problem is back.
I applied the patch when It was version 6.2 and the problem was fixed.
the patch is still included in composer.json "enable-patching": true,
"patches": {
"drupal/webform": {
"Add signature as attachement2": "
https://www.drupal.org/files/issues/2023-05-19/3303027-signature-attachm... →
"
}
}
},
