I have been using Wise for several years now and it was always a few hours or if transferring for long term stay in Thailand the next day. This month I got the same micro deposit explanation; it ended up taking 6 days. They did apologize and gave me a free transfer up to 1000 GBP about 1300 USD so that was cool, did a transfer today and the same thing it will be 6 days again. The last time this happened the $ was up vs the Baht. Could the reason be they are low in Baht supply and don't want to buy?
