Had an experience recently where one interface for a dapp did not work, and I was able to extract funds by switching to a different interface, and if even that had failed there were other workarounds like monkeying around with etherscan's "write contract" feature.

Decentralization and openness are amazing.

Had a similar experience when trying to retrieve ETH from an old SAFE contract, the old interface was sunsetted and the new one was not supporting it. In my case, thankfully Infura was hosting an old version of the interface so that helped, but also could have interacted with the contract directly too.
