Don't use smileys etc. on AMP pages
Yesterday I set up my website to AMP pages. I sometimes use a smiley in a post or page. And I suddenly saw it looks terrible on the AMP version.
Thinking that this might apply to other signs than smileys. So just a warning if you are using smileys etc. to check how it looks in the AMP version.
Here is a screenshot so you can see how it looked on my phone, and as you can see it looks terrible, so if you check if there is any signs etc you need to change after setting up AMP.
All the best,
