Unable to play video in theme Kate blog when I edit w/ Elementor

To whom it may concern:

Hi. I read the previous post about not able to embed a video w/ Elementor in (posted 1 year and 2 months ago) and I followed the steps by adding the CCS code:
.elementor-wrapper.elementor-fit-aspect-ratio.elementor-open-inline > div {
max-width: 100%;
}

.elementor-wrapper.elementor-fit-aspect-ratio.elementor-open-inline > div > div {
padding-bottom: 52%;
}

However, my video will play in Elementor page but won’t play it in my blog. Could someone help me and see what could went wrong with my blog/setting please? Thank you!
