I asked Wise to Tag My Account as always needing transfers tagged as international or ftt. I also use long term stay in Thailand as reason for transfer. I transfer to Bangkok Bank and for 16 months there has been no issue. Both my banking app and bank book show ftt transfers. Transfers to other banks were hit and miss. Swift transfers resulted in my uk current account being closed!

0 baht. I have just done it and the only complication was that they wanted my uk bank statements to prove where the transfers had come from. It took over an hour for them to check payments out matched payments in. They did not not ask for Wise transfer documents. I also had to provide a copy of my bank book with a transaction on the day which I got from the bank. Nothing else was required from the bank as they accepted the statements I printed out myself ordered from the banking app.
It all went very smoothly but some offices do not accept monthly transfers so make sure you check yours does. I hope that helps and good luck.
