Al Quran - Tafsir & By Word

I tried several times to download audio for this app but could not download any qari recitation. I asked this question several times during last 2 years but did not get any feedback. Hope to hear from you this time. Exception: Ayman Suwaid, Bangla/Urdu translation audio works [served from different servers]

My tafsir ibn kathir shows it's at 0 mb. When tafsir ibn kathir is turned on while I am in a surah or when I click a/ go to a surah it won't show anything of the surah. Pure nothingness with background color only and the buttons at the bottom and the top only. However when I scroll to the side (as in going to another surah) it shows the translations and tafsirs but without the tafsir ibn kathir, but only for the surahs in the left and right of the first (where I turned it on).
