Leaderboard Creator

I see this same issue! Been wondering why it seems to drop for like 30 min a day!

My solution to this was to adjust my game to store a player's personal best, so whenever they open the leaderboards, and the servers are working fine, it'll compare their stored best vs. their uploaded best, and if their store score is better, it'll give them a button to upload their new personal best.

It was originally something I created to allow players to play offline, but upload their score later.

You should not be storing the full sprite in string, you should create some kind of ID for a sprite in a scriptableObject or something and save that in the extras. I created a little class that helps me store data in a single string in a KvP way, hope it helps:

public class SingleStringKvP
{
    private readonly Dictionary<string, string> _kvPairs = new();
        private const char PairSeparator = ';';
    private const char KeyValueSeparator = ':';
        public SingleStringKvP(string startingValue)
    {
        Parse(startingValue);
    }
    public SingleStringKvP()
    {
    }
        public void AddValue(string key, string value)
    {
        _kvPairs[key] = value;
    }
        public string GetValue(string key)
    {
        return _kvPairs.TryGetValue(key, out var value) ? value : string.Empty;
    }
        public override string ToString()
    {
        var builder = new StringBuilder();
        foreach (var kvp in _kvPairs)
        {
            if (builder.Length > 0)
                builder.Append(PairSeparator);
            builder.Append($"{kvp.Key}{KeyValueSeparator}{kvp.Value}");
        }
        return builder.ToString();
    }
        private void Parse(string startingValue)
    {
        if (string.IsNullOrEmpty(startingValue)) return;
        var pairs = startingValue.Split(PairSeparator);
        foreach (var pair in pairs)
        {
            var kv = pair.Split(KeyValueSeparator);
            if (kv.Length == 2)
            {
                var key = kv[0];
                var value = kv[1];
                AddValue(key, value);
            }
        }
    }
}
