Is the online NON-O extension of stay system at Chiang Mai immigration currently functional?

The online extension of stay system for NON-O visas in Chiang Mai appears to be problematic. Users have reported that the only option available for online extensions is "retirement," while other categories like marriage or raising Thai children are not accessible. Furthermore, some users noted the absence of available bookings for both July and August, suggesting that the system may not be functioning properly. It was also mentioned that the Chiang Mai immigration office had ceased taking online bookings for Family Purpose extensions earlier in the year due to staff reallocations and increased office traffic.
