iPad signature in email or outlook with company or organisation logo.

Hi,

I have been trying to add my logo signature in email signatures but for some reason it accepts the logo initially and then when you go to type your email it disappears. When going back to settings mail and accounts signature the text is there but the images/ logo has gone and now appears as empty boxes.

I watched several YouTube videos and pasted the logo shaken the devices but it still does not save the company logo in the signature field.

I have also tried using outlook App, Gmail, Outlook Owa (which no longer works) and non of these seem to support the logo signatures.

please help, I am a provisional driving instructor and will be running my business from the car between pupils, want a professional image when I finally can qualify as a Approved Driving Instructor.
