After installing google tag manager in my website, open the website in the browser, for example: abc.com, and then switch to other browser tab page, wait for the tab of abc.com to enter the sleep period, and then go back to the page of abc.com again, you will find that the page is stuck, and it is useless to refresh, you can only open a new one! After a day’s test, it is because of the Google tag manager, have you encountered similar problems?
When I removed the google tag manager, he worked fine!
