Fuck opensea. When you're the main site for NFT transactions, raking in as much as they do, there shouldn't be any hiccups.
I haven't been able to see my full collection on my pages in at least a week now.
I'll be moving to looksrare.org. They've got a token (which opensea will NEVER have) to reward users on top of staking rewards.
Worth checking out.
looksrare.org has indeed lot of variety of NFTs and also is user friendly unlike Opensea.
