Realm Resource Packs have to be redownloaded every time joining

My friends and I have a realm with a few resource packs - changing music discs, grass textures, etc. Every time I or my friend - who are both on Xbox - join the realm, we have to redownload the same packs (which takes quite a while). Once we get in, everything works fine. My friends who play on PS4/PS5 had to download the packs once, but haven't had to since.
