When automatically creating a GA4 (https://i.sstatic.net/AH0I9.png), are all accesses from the past (source resource) transferred or not?
For example: There is a UA resource that I only have read access to. If I automatically create a GA4 resource for it, will I have the same level of access to the new GA4 resource?
There's nothing in here about accesses: https://support.google.com/analytics/answer/12938611?hl=en
If you are opting in
for automatically creating a GA4 property:
property-level
users will be copied over and have the same level of access as that of the UA property. (Only users who have access to the UA property will be copied over and will retain access to the new GA4 property)view level
access, they won't have any access to the new GA4 propertyYour new Google Analytics 4 property will have the same Universal Analytics property-level users with equivalent permissions. View-level users won't be copied.
