[UK] Plaid + Amex & missing transactions

I'm in the third year using YNAB.
I started having to get "adjustments" when reconciling my Amex account (Plaid, UK) since moving away from TrueLayer.

Last one today, I realised the (small) adjustment is necessary because one transaction is missing.
Checked the previous adjustments: same story.

Anyone else in the UK experiencing random missing transactions with Amex+Plaid?

Other accounts I have linked seem ok.
Thanks.
