So, Through this app, I've tried changing the text styles into "Bold", "Italic", "Strikethrough" by the parallel slide it offers just above the keyboard. But none of them works when Commenting on a post.

This is the very first time I'm officially testing the text styles in post.

This line should appear Bold

This one should be Italic

~~This one should be Strikethrough~~

^superscripst^

~subscript~

If the upper 5 lines don't appear as different text style to you or to me, then what can be concluded from this? Is this the app's incompatibility or my device's incompatibility?

Additionally I'll try all the 5 styles in comments. Since I don't know if only I cannot see the effects from the app and others CAN see. Respose accordingly please.

Edit: PROBLEM SOLVED
