Experience transferring to HiveOn pool for mining

I've mined RVN for quite a while with HiveOS rigs. They were using Flypool. The other day I got a random message from them saying my balance was low. I didn't think much of it but I got it a few days in a row. After checking on them, HiveOS suddenly started charging me for mining with HiveOS when connected to Flypool. This is just their policy, so I get it, but it's pretty lame they didn't give me any heads up about this whatsoever.

So I switched to use their pool. Normally pulling like 500 RVN/day. But uh.. I only got like 60 in the last 24 hrs. Feeling super ripped off. Not sure how to prove it. I notice that I'm accepting way fewer shares than on Flypool. I know the hashrate has gone up recently too so that's probably also a factor, but it shouldn't have gone up THAT much. Anyone else think they're getting ripped off on the Hive On Pool?
