There is some sort of registration system where a home/condo owner can register a tenant online - the printout can be used at immigration for residence cert. What system is that? How to sign up?

When going to the Thailand Pass site, do you have to fill it out completely at one time? Or can you save what documents you’ve downloaded, and then come back later to finish it? Thanks in advance.

TM30 online error messages - have looked through old posts on this and can't find one to specifically help. Any help documents available in english about why I keep getting error messages when try to save.

I've tried on chrome, and IE. Both typing in online and uploading form and keep getting error messages when try to save. My (thai) husband is no use helping me and my assistant obviously off work today to help me register at where I live at the weekends, and when she tried last time online on a Monday said wasn't within 24 hours so she couldn't do.

Is there an app for iphone yet that might work? Getting ready to throw my laptop at the wall!!!!!

TIA.

*** update. Still couldn’t download app, but my assistant managed to do for me so need to check with her what I was doing wrong.
