Don't open krung thai there app is useless my philippine wife got stuck in Lao on a visa trip when her krung thai app went down very unhelpfull help line useless bank
no need to stay if you don't want to I just used to go for a nice malay mutton curry and a bottle of Guinness and stamp back into Thailand after a couple of hours
pretty sure thailand did have this rule in place in the past
Philippine is though far worse than thailand getting papers and permits for every thing
I know my wife had to get a paper from the philippine embassy in bangkok saying she had employment in thailand or she would'nt be allowed to to come back after a holiday to see her family
