Is the 90-day reporting app in Thailand experiencing issues with email validation?

A user is experiencing difficulties with the Thai 90-day reporting app, specifically with email acceptance. Comments suggest common issues such as ensuring the report was made in person, checking the email used previously, disabling pop-up blockers, and being within the correct reporting timeframe. It is advised that reports should be submitted within 15 to 7 days before the due date, and if issues persist, visiting the Immigration Office might be necessary to resolve the matter.
