I have a Bedrock realm, with Minecraft 1.18.2 on my PS4. I found a double spawner: skeletons and spiders. Before the upgrade to 1.18, these spawned just fine, most of the time. Now they've completely stopped. Running in survival, hard mode. Rebooted the PS4 and the realm several times. Went away from the spawner for a couple of days. Getting plenty of mobs elsewhere. Just not from any spawners. I'm AFK-ing behind glass panes, alternating with a minecart on powered rails, with both half block and full block openings, within 7 blocks of the spawners. I can ride or stand around for an hour without a single mob spawning.
