Just wanted to share my failed experience of applying for an extension of stay. Tried applying in Chiang Mai today March 25th. Got rejected because Wise is not considered a real bank. Same goes for Revolut. You gotta provide a bank statement from a "real" bank is what I'm told. This + all the original docs you used to apply for the DTV + rental agreement here in Thailand + certificate of bank account ownership + proof that I've been paying rent here in Thailand.
Hope this helps!
EDIT: I successfully left the country and came back 3 days later. Upon reentry the immigration officer asked for proof of accommodation. Nothing else aside from the obvious (passport + printout of evisa).
