Hi! This just means you are sending too many data requests and DataStoreService is having issues processing the new data. Usually nothing to worry about, but on larger games, this becomes an issue!
I’d recommend Profile Service. It’s a little tricky at first but it works REALLY well even when roblox is having issues. For example, it will not load data if roblox data stores are down. Its a useful module, you should give it a try. Hope this helps!
