I have been using bulletproof buttons for a long time. I went to make an update to an older email and noticed that on click my buttons turn blue. I cannot figure out why this is now happenening. Any suggestions for a fix?

I tried redoing my button in case I had somehow changed something but it did not resolve the issue.

I generated this code here: https://buttons.cm/

<div><!--[if mso]>
  <v:roundrect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" href="#" style="height:45px;v-text-anchor:middle;width:230px;" arcsize="20%" stroke="f" fill="t">
    <v:fill type="tile" src="" color="#fed115" />
    <w:anchorlock/>
    <center style="color:#000000;font-family:sans-serif;font-size:13px;font-weight:bold;">Take me to my account</center>
  </v:roundrect>
<![endif]--><a href="#"
style="background-color:#fed115;background-image:url();border-radius:9px;color:#000000;display:inline-block;font-family:sans-serif;font-size:13px;font-weight:bold;line-height:45px;text-align:center;text-decoration:none;width:230px;-webkit-text-size-adjust:none;mso-hide:all;">Take me to my account</a></div>
