After testing it like this, I found that there is no problem. It is recommended that you trace the code to determine whether you have logged in. Is there any cache or other factors that may affect it?

Is there any problem with the login status judgment of total?

Consider whether it is the impact of caching.
Check to see if the points have indeed increased twice in the background. If it does not increase the second time, it means that your background logic is correct, and it may be caused by browser cache. If the background is indeed increased, then the background logic is wrong.
