Another glitch?

Just spent £39.99 at Amazon. This has appeared twice in my Tymit app - both as pending. Amazon has messaged me and said the payment has declined.

I’m well within my credit limit and everything else is OK. I have been spending at Amazon with Tymit card with no problems over last few weeks.

Anyone know what is going on - is it just ANOTHER Tymit glitch :man_facepalming:t3:
