Bugs in content types

Currently the Accordion content type editor has options for creating H2, H3, and H4s for the accordion toggles.

There should also be an non-heading option such as <P> or <SPAN>. When an accordion is inserted into a page of content, the heading will often break the surrounding document structure (i.e. the heading sequence), inserting a heading where none is expected.  Sometimes the author can predict where the accordion will be placed, and guess which heading to use so it fits the heading sequence on the page of content.

It works beautifully on my desktop and latop, but on my Amazon fire, Oneplus 9 pro and other phones it doesn't work.

I really need it to work, I have installed the latest chrome version 90 , but still not.

Anyone else encounter this issue, is there anything I might be doing wrong

LaTeX code like \( x = 1 \) or $$ x = 1 $$ is not resolved at all in content type Mark the Words. It is displayed simply as code.
