Or do you have a mobile wallet like Breez which you use for quick zaps?
I've been using the Breez wallet for a while, I've made a lot of lightning transfers with it, but I have a balance stuck that I can't get out of for some reason. The Breez wallet forced the channel to close, the transaction was confirmed on the blockchain, but I never received the funds again, and to top it off, the wallet never syncs 100%. For 2 years now, I've been trying to re-sync the wallet from time to time in the hope of getting my funds back.
Luckily I didn't lose much, I think around .0006 btc.
OP, About the coinbase wallet, as other members said, I'd stay away from this wallet because it is closed source, use open source wallets, at least you can verify them.
Recommended Wallets for iOS: BlueWallet, Blockstream Green (Green Wallet), Stack Wallet (or Stack Duo).
