Constrain Days Ahead By 1 Day

So the automation below has been working for a long time:

    def initialize(self):
        time = datetime.time(19, 30, 0)
        self.run_daily(self.first_notification, time, constrain_days="sun,mon,tue,wed,thu")

After the update to 4, this doesn’t work. So I did some testing and it seems to be 1 day ahead; as the below works :

    def initialize(self):
        time_to_run = datetime.time(21, 51, 0)
        self.run_daily(self.func, time_to_run, constrain_days="fri")  # tomorrow

    def func(self, kwargs):
        self.log(datetime.datetime.now())
        self.log(datetime.datetime.now().today().weekday())

# returned: 2020-01-23 21:51:00.049272 INFO testing: 2020-01-23 21:51:00.046546
#           2020-01-23 21:51:00.061440 INFO testing: 3

But this, which is the actual day, doesn’t work:

    def initialize(self):
        time_to_run = datetime.time(21, 51, 0)
        self.run_daily(self.func, time_to_run, constrain_days="thu")   # the actual day

    def func(self, kwargs):
        self.log(datetime.datetime.now())
        self.log(datetime.datetime.now().today().weekday())

# returned: nothing

So not sure what is going on, what am I missing or is this a bug?

Edit: Additional info to help track this down. I tested this again the next day in the morning (10am) and all worked as expected; testing again just now (8:30pm) and it is all 1 day ahead as shown above. So its probably after 12 noon when it makes the change…

Does this issue still exist for you? I think it does for me in v4.2.1

Sorry for the late response.

Yes, this issue still exists for me. I was not able to figure it out and gave up since I could get it to work if I just set it up to be a day off.
