My bank statement is as expected, no transactions listed. They were approved but I cancelled them after approval when there was no Proceed method to move forward in the Trading 212 UI. VISA did confirm the transaction was cancelled which was nice.
Also a good job as I tried 3 times 
- I didn’t want to continue trying as the automated security could flag an anomaly seeing multiple transaction attempts being approved then cancelled. This could lead to the account being temporarily blocked.
