We recently noted a bug in Gmail App IMAP: our red button CTA renders without copy in it. It is only happening in Gmail App IMAP Android 4.4

We use to code the CTA in this way to make it clickable on Outlook:

<a href="URL" style="color:#ffffff; text-decoration:none;" >
<table cellspacing="0" cellpadding="0" border="0" align="center" style="margin:0 auto;">
<td align="center" bgcolor="#d83b01" style="font-family:'Arial'; font-size:16px; mso-line-height-rule:exactly; line-height:20px; color:#fffff1; padding-top:10px; padding-left:40px; padding-right:40px; padding-bottom:10px;">
<a href="URL" style="color:#ffffff; text-decoration:none;" ><span style="color:#ffffff; text-decoration:none;">CTA copy</span></a>

It looks like the wrapping <a> tag get closed in the wrong spot in the rendered email. Any thoughts? Thanks!
