Thank you so much, @Prasant! So that^ really helped, and the icons are now appearing! I am having one more issue still, unfortunately.
I'd like to ensure that the x theme is validated on my new website on Bluehost. I followed the process provided here to assign to the new domain (uvc.tv), away from the old domain (uniquevideocreations.tv). However, the dashboard for uvc.tv still states that the theme is not yet validated.
So, I went back to WordPress.com and logged in to uniquevideocreations.tv to see if there is any way for me to unassign the theme over there, but I couldn't find a way. By the way, just so you know in case this helps, I'm in the process of moving the website away from uniquevideocreations.tv (WordPress.com) and over to uvc.tv (Bluehost). So the uniquevideocreations.tv will be closed in a few days, and I will only be using the theme in one place, uvc.tv.
Additionally, again in case this info helps, I noticed that the website URL on Bluehost had been set as "https://www.uvc.tv" and I changed it to "https://uvc.tv" - and I made sure to reflect this URL change in the Themeco licenses settings as well. Just letting you know in case this may be causing any issues by any chance (I'm not sure if this matters, but I only did this because I want to make sure visitors are able to get to our site regardless of whether they type in the "www" part.).
Thank you so much, again, for your help! You're a rockstar.
EDIT: My apologies, @Prasant! I actually just tried it again and it worked! The theme appears to be validated on uvc.tv now, so I can close down uniquevideocreations.tv with peace Thank you, sir, for all your help!
