No worries - I did publish through Travelfeed.io.
I don't recall reading anything on not being able to edit using another front end, but I'm still learning and there is info overload in an ever evolving product - Still, it's your upvote to control so I accept this.
I have posted on your help line about why I edited with other front-end (will attempt the method expressed in response, but it didnt work previously for me - this must be a new improvement?).I also couldn't find an answer to my specific question around a double image and text appearing on other front ends (I'm sure its just me but I want the max audience and need my posts to appear fine on other front ends).
As I know you guys are hard at work developing and improving it cant be easy; Still, I will be reviewing my witness votes (including proxy) and delegation shortly & will be watching/considering what you do in this space with great interest.
