Block "Share" slows down?

Question

Yandex

The site has a block from Yandex with social buttons.
At first everything was fine, the pages of the site loaded quickly. But now I noticed that the page opens just as quickly, but the loading icon continues to spin for a very long time. The buttons themselves also load quickly.
I checked, removed the script and the pages open in a swoop. Everything works perfectly. I go to the designer of these buttons and observe the same picture - the Yandex page with the buttons takes just as long to load, or rather the content opens quickly, but the loading icon spins for about half a minute. It turns out that the "Share" script is somehow slowing down the loading of the site.
Tried on different computers. Equally. I do not rule out that this may be my local problem.
Has anyone experienced this, is there a solution?

Answer 1

change the script loading code to asynchronous - will solve the problem
