Hey gabbasp
There was a delay with AMEX bank feed transactions yesterday, check this post out for more information. However, if you're experiencing transactions missing for the last 6 days it may be worth raising a support request from your My Account dashboard. If transactions are missing for an extended date range we can take a deeper look and resolve accordingly.
For future, updates around bank feed delays will be posted in this Bank Feed Updates board - I'd recommend hitting the bell icon on the top right to stay updated with email updates.
