*tl;dr: We'll be stripping all content contained inside brackets from the
first sentence of articles in the Wikipedia app.*
The Mobile Apps Team is focussed on making the app a beautiful and engaging
reader experience, and trying to support use cases like wanting to look
something up quickly to find what it is. Unfortunately, there are several
aspects of Wikipedia at present that are actively detrimental to that goal.
One example of this are the lead sentences.
As mentioned in the other thread on this matter
lead sentences are poorly formatted and contain information that is
detrimental to quickly looking up a topic. The team did a quick audit
the information available inside brackets in the first sentences, and
typically it is pronunciation information which is probably better placed
in the infobox rather than breaking up the first sentence. The other
problem is that this information was typically inserted and previewed on a
platform where space is not at a premium, and that calculation is different
on mobile devices.
In order to better serve the quick lookup use case, the team has reached
the decision to strip anything inside brackets in the first sentence of
articles in the Wikipedia app.
Stripping content is not a decision to be made lightly. People took the
time to write it, and that should be respected. We realise this is
controversial. That said, it's the opinion of the team that the problem is
pretty clear: this content is not optimised for users quickly looking
things up on mobile devices at all, and will take a long time to solve
through alternative means. A quicker solution is required.
The screenshots below are mockups of the before and after of the change.
These are not final, I just put them together quickly to illustrate what
I'm talking about.

There is an IRC office hour scheduled next week to discuss
improvements to the mobile MediaWiki web site for contribution tools
and workflows. It will be from 16:00-17:00 UTC Monday 25 June 2018.
Links to join are on Meta. 
The Readers web team would like to make more contribution tools (like
Special: pages) available on mobile. Come talk to us about what you
want to see the most. More information on what we'd like to discuss
can be found on MediaWiki.org. 
I hope you can make it. If not, please take a look at the project page
and leave any comments on the talk page.
