Hextech Chest -Says Next One Available in 3 days yet still earned my (3rd) chest but never showed up

Hextech Chest -Says Next One Available in 3 days yet still earned my (3rd) chest but never showed up. After I earned my second chest the highlighted hextech chest icons in my profile had 2 remaining (obviously) an it said my next chest was available in 3 days. I earned another chest last night through one of my teammates getting an S rank and it removed it from my highlighted hextech chest icons (only 1 left) but it never showed up in my inventory. Is this a glitch or will it show up after the 3 day period has expired? This is a design issue that needs addressing. If your going to gate us on earning chests rapidly(understandable) because you don't want a player to earn them all in one day etc you should set a limit of earning 1 per week. I don't see the point in letting me earn all my chests in a single day and having to wait to get them. If I get them all in one day an have to wait till next month I still have to obtain the key fragments. In fact your current distribution method probably lowers your revenue as a user might be more apt to purchase a key if they had 4 chests waiting to be opened vs not getting them for days an getting the key fragments in the interim.
