TM30 online.
I just did my TM30 online.(Phuket) and it's working. I saved it, retrieved the entry and printed it. I checked both ways, webpage and section 38 app. Both working today.
TLDR : Answer Summary
The TM30 can be successfully filed online through the official immigration portal or the Section 38 app (available on both iOS and Android). It must be submitted within one business day after moving to a new residence in Thailand. Users have reported successful submissions and retrieval of their TM30 details, noting that it's important to disable VPNs and pop-up blockers while filling out the form. Screenshots of completed TM30s can be useful for visa applications and extensions. However, some users have experienced issues with the app not displaying their TM30.
