Tag list null on iOS

When I try to add a tag to a task in the iPhone app, the tag list is null. Our organization has lots of tags, and I should see the same tag list on my laptop and iPhone.
On my laptop, the list seems to be dynamically generated, from tags in use. WHR doesn’t that happen on iPhone?

That should have been Why, not WHR

Hi @Alina_Hsu and thank you for taking time to report this!

If you try typing the first letter of the Tag you want to add, a list of all tags starting with that letter will be displayed.

I hope this helps! Let me know if it works for you.

OIt works, but only if I know what tags exist! The tag list should populate like it does on the web version.
