Could this describe your problem:

There is not necessarily a timely or definite link between time zone 
data updates and package or OS time zone updates, as the lead time for 
propagation varies greatly, especially to vendor mobile platforms 
depending on their age, quality of the product implementations using 
that data varies, and may depend also on the programming language of the 
implementation, some of which use the data in their own ways.

This project provides a reference implementation, typically only used 
directly in open source Unix-like environments, and at best only as a 
basis by proprietary product vendors.

Your best approach is to contact your time keeping or scheduling project 
or product vendor support forum or mailing list.
The best this project can do may be to point you to a point of contact 
for the appropriate support organization, given sufficient information 
about your environment and issue.

Please also state the time zone selection named in the product with the 
issue, and the issue in terms of what you see or set, and what you 
expect, giving explicit dates and times?

Please also give your Device, Platform, OS, Version, Edition, Service 
Level e.g. Mobile Samsung Galaxy S22 Android 12 2022-08, Mobile Apple 
iPhone 12 iOS 16.1, Desktop MS Windows 10 Home 21H2/2009 
10.0.19044.1889, etc.; and your Product, Edition, Version e.g. MS 
Outlook Windows/Mac 365/Web/Desktop 9.99, and/or MS Exchange, and/or MS 
Findtime, and/or MS Calendar.Help, and/or MS Cortana, ..., etc.?
