@sid, I have the same thing going on.
It seems to only happen in Chrome, and not Firefox. It started happening in the last 3-4 weeks and never happened before. I’ve gone back to versions of my app where this was never a problem, but those versions have this issue too in Chrome.
I really need to find a fix too.
My app is based on Wappler 3.9.7.
The some issue occurs on my test site based on 6.0 beta.
@patrick, would really appreciate your support in this. I think there is some part of App Connect that Chrome has taken a dislike to. Can you help us find it and work with Google to find a solution? 
You can use your login to my app at:

Thank you!
Antony.
