All of the preloaded dictionary for the Thai language use
this symbol " ํ " (which is rarely used to nearly non-existent in Thai) plus this vowel " า " instead of
a single vowel " ำ ".
so all words including very common words like water "น้ำ", remember "จำ" are not available in both typing and gesture flow.
This issue is quite buggy and a nuisance.
