Describe the bug

Hello. First, thank you for this wonderful product. I can imagine leaving Inoreader for Filo if the following problems get fixed:

Problem 1:
https://www.bta.bg/bg/rss/free
This feed skips new articles (not all new items get displayed in the timeline.
Besides, it does not display the pictures in the articles, which are being displayed on every other rss reader
Problem 2:
https://www.nzz.ch/startseite.rss
-Not displaying all pictures in the articles
-skips new articles in the timeline
-The article thumbnails are not being displayed

Please help. I like everything else in Folo.

Thank you!
Big fan

Start by reproducing the two reported feeds, https://www.bta.bg/bg/rss/free and https://www.nzz.ch/startseite.rss, in the iOS app and compare the timeline and article display with another RSS reader. Done means new items are not skipped and article images and thumbnails appear for both feeds; no source files or tests are identified in the report.
