If this god awful site wasnt riddled with enough problems - so much so only log in and leave - on day 6 of the daily login streak, it tells me ive lost the streak. What a fucking disgrace of a site.
It worked for me without any problems. But you have to make sure that you log in on time, as whale does not follow the user's time zone. So if you live in a time zone that is very different from Whale's, it can happen that the next day has already begun for Whale.
However, as @AHOYBRAUSE has already correctly pointed out, the loss is not too great, the rewards from the Daily Streak are currently not that high, but rather an additional nice motivation to log in.
