Need help - font/size of native email app

[Tran Trung Le]

Hello everyone, I am using LG native email app for my company email. However, when I reply/compose email, the font and size of texts are always different from the signature, and it makes my email look funny due to font/size difference.
Can anyone help to advise how to correct this? I attached a picture as an example. The text 'Hello' has different font/size from my signature.

Problem fixed! Just changed the signature again.
