PNG file with auto signature on email
I have an Ipad running the latest IOS and an Iphone SE on the latest IOS. Although I can create an autosignature with my business logo png on the Macbook Pro (mid 2012 running Catalina) the Iphone and Ipad won't show the logo although it's there initially when I paste it on the settings signature. Ive managed to save the png onto the 2 devices but what else do I need to do to have the logo in place on the mobile devices? Thanks for your help.
iPhone SE, 13
