Comment to 'The function "Add" unfortunately does not work.'
  • I solved the problem myself. At first, I just turned off the Add block and turned it on again. After this action, the problem was resolved on the version of the site in the laptop. But the problem remained on the mobile version. I decided to enter my site not with Google Chrome, but with Yandex and everything began to work fine. It turns out that in my mobile Huawei based on android the Google Chrome browser does not work correctly.
