Spotted wolves not spawning (not really fixed?)

Spotted wolves aren't spawing at all, I used chunk base to verify I was in savvanah plateau). I saw another android bedrock user report the same issue though it was declared duplicate and resolved to a different Java report. However I am thinking it isn't actually solved for bedrock users. I have walked around in circles in different savvanah plateau biomes for over 2 hours and still none have spawned. Llama and armadillos do (along with rusty wolf in sparse jungles and woods wolf in woods).

UPDATE: I got some to spawn the only different thing I did when returning to plateau was have the world on easy instead of peaceful (during day). Similarly couldn't find stripped wolf in wooded badlands till turning the gamemode on easy
