PHP Functions

Hello

I Changed :
“secondary_title_use_in_permalinks” => “off”,
to
“secondary_title_use_in_permalinks” => “on”,

but in permalinks nothing changed. why?

and one more thing
in the main setting of plugin i used “<span style=”font-size:14px;”>%secondary_title%<br><span style=”font-weight:700;font-size:14px;”>%title%</span>” to set style for my posts but have a little problem , when we share the post link in Telegram , it shows the <span style=”font-size:14px;”> whit the title of posts
Here is example https://imgur.com/a/wtoHvoJ

now where should I add the style to show my Secondary Title and my Post Title whit specific style ?

Thank you.
