After updating my existing world (running on a BDS) to 1.17.30, iron golems no longer spawn in my iron farm. I created a test world on my iPad to test iron farm designs, and I can't get iron golems to spawn, only cats. I've left plenty of space for golems to spawn, two levels (both safely within the 6-block vertical space) for them to spawn on, but all I get are cats. Difficulty is normal, mob spawning and daylight cycle are on. Beds are centered in the farm, villagers are linked to the beds and are refreshing their trades. Everything is working as it should except for iron golem spawning.

Update: I got iron golems spawning again after I removed 2 villagers. It seems I had more villagers than beds and that killed iron golem spawning. That seems an odd behavior.
Glad you got your farm working. Iron golem spawning does require that every villager in the village has a bed. That is stated as an intended requirement in the 1.16.0 changelog: https://feedback.minecraft.net/hc/en-us/articles/360044928311-Minecraft-Nether-Update-1-16-0-Bedrock-
Does MCPE-140244 describe your issue?
Getting cats but not golems usually means not enough villagers are working. This could be because a baby was born or a villager nearby that you didn’t intend to be part of the farm is treated as a dweller if the village by the game. Those would be problems with design and construction, not bugs.
If you still think you have an independent bug happening, a copy of the world save would be best way for us to investigate. We need steps to reproduce the problem in order to confirm a bug.
