Mobile layout issues with Jetpack 10.3

After the Jetpack update (from version 10.2.1 to 10.3), it appears some of my site pages are not rendering correctly when viewed on a mobile phone.

On the main home page, the word ‘IT’ in ‘It Service Management Best Practices” now has the ‘I’ next to the image instead of next to the ‘T’, below the image.

Also, on the Contact Us page (https://www.wildewoodconsulting.com/contact-us/), the company name and the ‘P.O.’ in ‘P.O. Box’ are to the right of the logo, jammed vertically on the side, and unreadable, instead of below the image.

These rendered properly prior to this update and I have tried fiddling with the text to get it to move below the image on the home page but can’t seem to fix it.

Any suggestions?
