Universal Filter Plugin No Longer Works?

Is anyone using the Universal Filter Plugin from Square Websites finding their code no longer works since the last Squarespace update, and the product filters have completely  vanished and been replaced with Squarespaces clunky product categories? I've tried removing and re-adding the code again but nothing is showing/working. This is occurring on both 7.0 and 7.1 websites.

Websites it has stopped working on:
https://www.giveadamngift.com/shop/
https://manorbarnorganics.com/shop

It's so disappointing that we've been screaming out for filters (price asc/des, newest, search bars etc) for commerce pages for years, and even paying for plugins like this, only for Squarespace to break them and still refuse to bring in these features.

Any help or feedback would be gratefully received. My clients are rightfully not happy (and right in the at the beginning of the Christmas sales period), so if anyone can suggest alternatives that still work too that would be amazing.

It looks fine. Can you explain it a bit detail?

Also, have you try contacting Michael in Slack Group yet?

It appears to be working from an outsider's perspective. Perhaps the issue is occurring only in the editor?

Thank you all for your super speedy replies! It's good to know if was still working for others if not for me/BT users. 

@paul2009 Bizarrely this was the issue! Both me and my client use BT as our provider in the UK. As soon as I replaced "assets" with "plugins" in the header code injection the filters all appeared again. Very strange, but so relieved this is working now. Thank you so much!

I also sent a to Squarespace as well requesting the product filters as a feature for commerce websites. Have been asking for this for years, but hopefully one day we'll get them.

You're welcome!
