I do have 2 queued transactions in metamask and 1 pending transaction. Do I need to cancel these somehow or I’ve read that uninstalling metamask and reinstalling it could work. If I was to do this would it impact anything or no?
Cheers 
I do get unknown processing time before I confirm the transaction on Metamask. Could it be to much congestion on the chain for the transactions to be successful with how little the transaction is worth?
I don’t want to keep trying to list NFT’s if I end up making my Metamask queue really long.
Thanks in advance.
I changed where it says listing price in ETH to listing price in MATIC.
I see, that won’t affect anything, it’s just text that’s shown in the app.

Yes you can cancel all of them. You can also reset your MetaMask account (Settings > Advanced > Reset Account).

I want to say it’s just network issues. Many other people have successfully used the marketplace boilerplate contract in the past. You can try another testnet like Goerli.

I’ve fixed the issue with the listing of NFT’s on Mumbai testnet. I still can’t list NFT’s on Ropsten testnet.
I have to figure out why it didn’t populate the marketItems part of my Database.
You will need to recreate the sync if you’re using a different chain.
I did recreate the sync for Mumbai and i still can’t get it to work. Could it be anything in my code or smart contract that I need to look at?
Cheers
