At 67 he should have had quite a few years of life ahead of him so it is sad that his life was cut short.
Nevertheless, hopefully, his death was instant and he was enjoying his life (and his new bike) right up to the end.
RIP Mr Edward.
I had the same problem.

On my browser the option to allow pop-ups appeared at the top of the page each time I tried to use the 90-day system, but I hadn't noticed it.
Visa on arrival and Visa exempt are two different things.
Taiwanese do not get visa exempt, they have to apply for visa on arrival.
Edit to add: Visa on arrival is normally 15 days.
Taiwan (Republic of China) is not recognised by Thailand. There are only about a dozen countries that do.
