Since upgrading to v3.2.4, we have seen that our messages are being delivered with random characters inserted at seemingly random points in the message. The characters are always a = sign followed by a space.
Here is an exa= mple of what it can l= ook like. Even HTML line breaks <= br> are affect= ed.
It affects both HTML and text messages. Sometimes the characters appear within an URL, rendering them useless.
Does anyone have any ideas what the issue might be? Thanks in advance for your help.
