reco for basic IPTV

Hi, Like many of us I used TVMucho for some time and subsequently Teeveeing. TVMucho is still loaded on my 4k amazon firestick and gave me teeveeing without any problems. however that gave up the ghost a couple of days ago .I have been trying to install Teeveeing which apparently has an app in APKpure.I am having trouble downloading this apk app due to the fact that I have absolutely no ides what I am doing despite web instructions. I would very much appreciate hearing from anyone who has successfully downloaded apkpure onto their firestick. Perhaps they can direct me to the instruction used. TIA

What I found helpful was using a downloader app that you can get right on the Firestick. With that app, you just plug in the URL for the APK you want, and it downloads directly. Super simple and saves a lot of hassle.
