Texture pack not loading in a realm

Hello mojang, 

I bought The texture pack pureBDcraft from the marketplace to download on my realm. I followed the instructions of applying a texture pack to a realm by making a copy of the realm and edit the texture pack in the copy and replace the existing realm with that one.

When I login to the realm the texture pack is still the vanilla one and nothing has changed.

I even reuploaded a backup of the realm and completely reset the realm but still nothing seems to work. 

My account name is: saharadomin

My realm name is: adventure

I tried this on my pc as wel as xbox one and nintendo switch

I hope for a reply as soon as possible. 

Kind regards, 

Saharadomin
