can’t add addon too realm

After about a whole months and a half of unable too add addons to my realm my summer was ruined i had all the great expectations and even spent almost 15USD on my realm hoping it would work but i tried almost everyday with no change even after the 1.19.21 update, i had gone through almost every post about realms since the start of all of this and there was only one fix that works with only a handful of addons - change the manifest for the resource and behavior to 1,17,0 but other then that that’s isn’t always a 100% solution and i was wondering if this could be a issue that is at the top of the list for fixes..
