Raven and Ledger Transactions

So I have been mining raven for a bit and my wallet is attached to my hard wallet.

Now I do not know how to code, my knowledge on that stuff is limited or basically nothing.

Now to the meat. I pay my buddy who is a taxi driver for rides in crypto. Mostly USDT, Firo, or if we bundle up 5 rides or so something like ETH. Well he just got into raven and I said "shoot, I have been mining raven so I'll pay you with that". Well I made my first transaction today out with raven and got "It looks there is a lot of data to parse. This occurs if you receive RVN from transactions with a lot of other outputs such as mining directly to your ledger. These long wait times are due to hardware limitations…"

So I was wondering why? When I mined other assets and send them there is no hardware limitations. Not trying to poo on the coin or anything just trying to understand why with this coin and my hard wallet there is such a bottle neck compared to my other assest.
