Confirmed with PS4/PS5 bedrock edition, world running on PS5.
World is not Experimental.
Difficultly is normal.
Version 1.17.30.
Skeleton spawner was setup on August 20th under 1.17.11, appeared to work fine, hard to fully know since had limited experience with it before the update to 1.17.30 on the 21st.
Since 1.17.30 randomly will work, if host is in overworld and goes to nether appears to break it, even if they return to overworld.
Have no other monster spawners to test if having same issue with.
Probably unrelated but adding, noticed with bee's that they weren't leaving the bee nest either. Didn't have bee hives to test with when noticed.

Skeleton spawner when working also only spawns like 3 at a time, with nearly max spawner wait. In the past noticed that spawners can sometimes pop out mobs, but with this, have a bubble column/drop chute, so can easily kill them and have to wait a bit for more to come in every time.
Also noticed when we went to the End Portal at -1100, 212 on the map, the silverfish spawner only spawned 1 silverfish, rather than the waves it normally does, destroyed that so unable to test with it further.
Had encountered several blaze spawners and were working, however only spent a little time with them, it seemed like they only spawned 1 at a time, and with nearly max spawner wait also.
Cave Spider spawners when encountered in a mineshaft also only had a few around it, and none spawned in time to torch it up.
Spawners work for a bit, but if leave the area have a chance for it to not work, haven't noticed any issues with crops not growing in any of the farms we have for it.
