Hey @Neosverse ,
I don’t think there is a way to add back in without manually re-adding, but I’ll confirm.
Assuming there are ways devs build something to do this for themselves. 100+ wallets is not general practice for most (as you’ve also said). One possible solution would be keeping a small amount of ETH in each wallet (not skipping any). The article @snwlprd.eth shared notes that accounts get added that have ETH in them on Ethereum Mainnet. Once MM hits one account without ETH it no longer restores (even accounts with ETH past that).
