Realm Rollback

I recently purchased a Minecraft Realm, for my friends and I to play on. However, each world we create has a rollback issue once more than a couple people play on the server. At first, only two of us were on the server and the issue did not occur for a little over a day. Once other people began playing on it as well every few hours the server stops saving backups and will rollback 4 or so hours. This is really starting to frustrate us as 5 or so people are putting 4 hours into the game; building, grinding, etc. and the server resets to the previous backup which is before any of that occurs. It has now rollbacked 12 times on us across two different worlds, and has become unplayable. It is getting to the point where none of us want to play on the realm which I recently purchased, and the realm will most likely expire before this issue can get resolved. (It is now essentially a waste of money.)
