after 19 August 2020 – in that day, Google Cloud Platform had some problem – Realtime overview report doesn’t work in my App+Web Property.
I have some APP+WEB Propeties in my account but this one has the problem only.
It says “A temporary error” but it still can’t load data for two weeks.
“Users in Last 30 Minutes” unit is working well in the other pages such as “Users overview”
If someone know finishing this situation, please let me know.
