Thanks for allowing me to clarify, Jakuje. On Nov. 25th, I completed:
* "The Sky is the Limit" in Tuskeegee, AL (5 Locations)
* "100 Years of Olympic Games" in Atlanta, GA (5 locations)
* "A Stroll Down the Famous Peachtree Street" in Atlanta, GA (10 locations)
* "Historic Oakland Cemetery" in Atlanta, GA (10 locations)
* "I Have a Dream" in Atlanta, GA (7 locations)
* "City of Buford" in Buford, GA (5 locations)
Checking my activity in the Adventure Labs shows my reviews for all of them on the 25th. However, two of the labs from "Historic Oakland Cemetery" (Margaret Mitchell and Tweet) are showing as discovered on the 26th. Additionally, all locations from "I Have a Dream" and "City of Buford" are showing on the 26th. Again, for these last two, I am seeing the expected date in my activity on the Adventure Labs app.
I hope that clarifies the issue a bit. Thanks for your assistance and patience.
