Your signature template appears to be broken or looks squashed when viewed on a mobile device.
This issue is caused by the screen size being smaller than the width of the signature - the fields within the signature template render as part of a table and will not wrap onto a new line.
To resolve this issue, add a fixed width to the signature template.
