Just returned back to Thailand from the UK, 1 week ago & no TM6 required. In fact they have placed notices, just before the Immigration desks, stating that it has been suspended. Straight through Immigration in less than a minute, using my re-entry stamp, no hassles at all.
After a couple of days at home, i needed to renew my Non 'O' "retirement' Visa & this was also completed with zero hassle, at Jomtien office. Just the usual paperwork, photo, Bank stuff etc required.
