javo spot e visual composer

Hello,
I’m new to the forum and I do not speak English well, so I’m using a translator.
if possible i would like to have a helper on the javo spot topic.
I would like to know why the tag read more in the articles does not work.
after the key back to does not work well on the smartphone.
because the text is not justified.
thank you in advance if I should receive a response.
