Today we released the updated cover video function built based on your suggestion, so you can now easily add/remove/edit cover videos from any previous or future post 😃
EasyEditor is a WYSIWYG editor (What You See Is What You Get). It doesn't support markdown, so if you try to use markdown syntax e.g. [link](https://link.com) it will just show what you typed. If you want to do things like insert links or formatting, you can do this in EasyEditor. We have a guide on using EasyEditor here: https://travelfeed.com/help/article/how-to-use-the-editor
Alternatively, you can also switch to the traditional markdown editor which works just like the one on other frontends, but we generally recommend using EasyEditor - once you're used to it, it's very powerful and allows for dynamic blocks such as image galleries.
Generally, it's best to edit your posts only on TravelFeed, they should look good on other frontends automatically. If there are problems e.g. with video embeds, please let me know before fixing it manually.
We use <figure> to show image captions on other frontends, the editing issue seems to be a bug in the hive.blog/steemit software, on other frontends like Peakd there are no issues.
