My upload keeps failing or crawling. Any tips before I call support?

A few things worth trying. Use "Upload Complete Folder" for big structured sets rather than dragging hundreds of loose files, and consider Relay Upload for genuinely massive transfers — it exists for assisted large uploads. Check your own connection stability, since a flaky upload will stall more often than the platform failing. And if you're pushing hundreds of gigabytes, reach out to support before you start rather than after it fails at hour three; the team has helped photographers with very large albums before, and a heads-up gets you a smoother ride.
