The manual shortcodes destroy my font size

Hi I love this plugin but it has a bug that I think is quite annoying, I explain, I always use the shortcodes in HTML to put the advertising manually … The problem is that if you put the code in the same line of text or just on the top, the font size becomes smaller. Here are a couple of example screenshots:

With a shortcode attached to the text:

<Many people think that Samsung is Android and nothing could be further from the truth…

With the shortcode attached to the text without a line in between the size is 16 Px compared to normal text which is 18, on PC you do not notice much but on mobile phones the lettering looks very very small and is very annoying.

If you leave a space the size (or if you disable the plugin) is the same throughout the text (18 Px). Please solve this problem, it’s given by the plugin that doesn’t encapsulate the shortcodes and devirtualise the text size, besides I’m surprised that with the good support you have you’ve never solved it because it’s a problem that takes several years. Well thank you very much for the support I hope you are having a good confinement and take into account my request for future updates, you just have to “shield” the shortcode so that it does not affect the text by HTML … Thank you very much !
