Trouble with 3DS

Has anyone else been having issues of late with the 3DS?

When I am asked to verify a purchase if I choose to verify via the app I login to the app via fingerprint but no alert is there.

If I select SMS it takes often 10 minutes for the SMS to arrive, by which time the purchase has timed out.

Twice now since the weekend I have had to switch payments to my Revolut card for this reason.

Is anyone else having similar issues or is it just me?
