[API] Same lastReadDate for all series #4180
Description
What happened?
Hello,
Using the /Series/on-deck and also the /Series/all-v2 endpoints, I noticed that the last reading date seems to be incorrect.
In fact, every last reading date seems to be the same for all the series in the list, down to the milliseconds.
That could not be humanly possible, and maybe there's a bug somewhere.
I think the date corresponds to a real date where I read 1 chapter, but it seems to apply to every chapters.
Could be that you're using an already existing instance of an object instead of creating a new one. Therefor, it's the memory address of the value and not the value itself being transferred.
I put an example of the output I got in the log.
Let me know if you need more info.
What did you expect?
