[2022] [Not a bug] Dungeon Jewel reward bonus missing

As @Tibo pointed out, this is how the rewards work for Dungeons and descending from the updated patch notes

Mini Bosses will get:

• +1 Shard every Level
• +1 Jewel every 4 Levels
• +1 Diamond every 20 Levels

While the Mega-Boss will get:

• +2 Shards every Level
• +1 Jewel every 2 Levels
• +1 Diamond every 10 Levels

Once you have reached level 10 if you have not seen an increase in the Mega Boss Diamonds please reach out.
