Ask Can a client file a refund claim after approving and downloading your work?

[Edward22]

I have seen situations where a client approves a delivery, downloads the files, and then comes back days later asking for a refund. It seems strange because the approval should mean they were satisfied. But some platforms still allow disputes even after that point, which leaves many freelancers confused about where they actually stand. Has anyone dealt with a refund claim after their work was already approved and downloaded, and how did the platform handle it?
