1. Get your Non-O before you travel to Thailand (valid for 90 days)
2. Arrive in Thailand (90 days entry stamp) and open a Thai bank account
3. Two months before you a apply for a 12 month extension transfer a minimum of 800k to your Thai account
4. Next month start the monthly transfers of 65k (this money can be withdrawn immediately if required)
5. Two months after depositing 800k apply for your 12 month extension with >800k in your Thai bank account
6. Get the extension stamped in and wait for another 3 months before withdrawing money below the 800k level (but never below 400k)
7. Two months before your next 12 month extension you will have a minimum of 400k in your bank account and a history of at least 12 monthly deposits of 65k or more to meet the requirements of the new extension. The 400k can be withdrawn when the extension is granted but maintain the 65k monthly transfers for subsequent extensions.
What has been delayed is the piloting of rhe ETA for Thailand originally planned for December. I have seen posts where this has been confused with the eVisa.
