This fill and sign function was normal before the Feb 2021 upgrade but now, I can't type any Thai Unicode using the Fill and sign function. However, the English language seems to be normal. When I typed in Thai, nothing appears at the cursor. Right now I'm using 'Add Text' under the 'Edit PDF' menu which is interchangeable but takes forever to load if using a low-resourced pc.
Is there any solution that I could try?
I'm trying to contact Adobe support but has no luck.
