Does the Chiang Mai Immigration Office require TM-30 updates after short-term travel?

The Chiang Mai Immigration Office (CM IO) may have different practices than other offices regarding the TM-30 form, which tracks the residence of foreigners in Thailand. Some community members report that they do not update their TM-30 after short trips within the country, especially if their residence remains unchanged. Users suggest that it is often unnecessary to update as long as you have the receipt, indicating that 'don't ask, don't tell' may work without issues.
