Hello @MaximC. Thank you for bringing this to our attention. I tested this out on my end and I was able to see the same thing happen on an Android. I brought this to our upper level of support and for the best display, they suggest not using a mobile browser to view emails but to instead use an app, such as the Gmail app. Mobile browsers are considered a "lite" version of a desktop browser and they may not be able to display all HTML emails correctly. I tested the email using a Gmail app and it does display correctly. Hope this helps!
