Divider Width Changes on Mobile in Zoho Campaigns

Divider Width Changes on Mobile in Zoho Campaigns

I am having trouble with the divider element in Zoho Campaigns. First, I do not understand what width I need to set it to so that it is exactly the same width as the text. I can only estimate it, and around 92% seems to look right.

However, when I send the campaign, the divider is indented even further on mobile devices, while the text remains correctly aligned.

Is this a known issue, and is there any workaround to make the divider match the text width consistently on both desktop and mobile?
