It's true, Andrew, I realized there is no description, when viewed from the App in the phone. However, when I go to edit the ad, I do have a written description. I don't know what happened. I'll have a look tomorrow via the P.C. I always had a written description ... Thanks for letting me know.
@Ana27651 There might be a weird glitch in the system, and actually a lot of functions don't work properly on the mobile app. Hopefully if you go back into the listing editor via PC, you can just hit save and properly publish the descriptions.
I also recommend adding captions to your photos, since the app features those more prominently than the written texts.
