We face the same issues for our clients. I wonder if importing a CAMT file would be easier. 

Especially if you have a client which is expecting to close the books on the 1st of the month and Saltedge didn't synchronize all the transactions yet. 

Same here.

Did you find an answer to your issue by now?

Edit: After trying again and again, Odoo finally synched with my back. I didn't do anything else than just try again and again.

Me too. Same versión. I was previously with Enablebanking connector which was awfull. Saltedge seem better but still a lot duplicates, lack of sincs, connection failures... I'm afraid the tool in general is not exactly the treasure they said. 

Oh! And comunity help is great, as you can see...
