Describe the Bug
When setting min value in the ion-datetime too for example today (28 september 2018) i can no longer select anything below 28, anything below september even though 1 januari 2019 should be perfectly fine.

Steps to Reproduce
Create a page with ion-datetime.
Set a min value to today.
Set the current date to today.
Select 2019.
Now try to select januari or any other month or date below today.

Expected Behavior
It looks like it does work if you first select 2019. Press done. Reselect the date input and than you can go to other dates that should work the first time. So the date input limits should update when selecting not after you've dismissed the input

Same issue with beta 7 and 11.

Still an issue in beta.17

enabled selections are not being refreshed properly
In my experience, the performance of ion-datetime min and max parameters is very poor. I am trying to limit selection of date from "tomorrow" to "one year in the future". For instance min="2018-12-05" and max="2019-12-04".

• if initial value is in 2019 - ion-datepicker allows me to select any month, even after I select year 2018 (it should be limited to 12th month only)
• if initial value is in 2018, I can only select 12th month, even after I move to year 2019 (i should be able to select any month in 2019)

see #14233

It seems that this is not a duplicate of #14233, correct? So I define it as new issue

[RHinderiks]

Indeed #14233 does not seem related to the minimum date settings

Hi there,

Thanks for the issue! I’ve added this to issue #16630 to keep track of. We’re going to close out the individual issues and address all of the Datetime issues at once. We’re not forgetting about your issue, just trying to keep them all together.

Thanks for using Ionic!
