This is a great request! We've been considering building out a managed auth flow and bank syncing, would love to chat for 15 minutes and learn from your use case. Does any of these times work for you this week https://calendly.com/letsfuse/fuse-demo-15, appreciate it!

In regards to coverage in the UK, we currently support Truelayer and we are building out a Tink and SaltEdge integration. They'll be available early next month.
