the new version of the Android app 1.212 (446) sometimes is not showing title pictures. The old version does, so here are two screenshots to compare both versions with the same feed (and same server and same app-settings):
This example shows this feed: https://www.tagesschau.de/xml/rss2
This problem is also true for all feeds from Flickr (example: https://www.flickr.com/services/feeds/groups_pool.gne?id=1034998@N22&lang=de-de&format=atom).
Tested on Android 6.0.1. Thank you very much for the hard work and this great app! If there are more informations I can provide, feel free to ask.
