I can't download mods and resource packs of the internet on Minecraft PE

I use the internet to download resource packs and behaviour packs for minecraft.They usually work but I have recently updated my iPad to IOS 13.1.3.The way the downloads convert to Minecraft are the same but when I download them they always say the resource pack failed to download because of the zip file being missing.I have tried several different sites and all of them are the same.Could someone help me fix this issue?
