Last Bullet List Item Not Displayed on iOS Devices

[shuvaevv]

On iOS devices, the last line of the bullet list is not showing up when the message is sent using blocks. This issue doesn't occur on desktop or Android devices where it displays as expected. (See screenshots and code provided below.)

Reproducible in:

The Slack SDK version

slack_sdk==3.27.1

Python runtime version

Python 3.11.7

OS info

Darwin Kernel Version 23.3.0: Wed Dec 20 21:28:58 PST 2023; root:xnu-10002.81.5~7/RELEASE_X86_64

Steps to reproduce:

import os
from slack_sdk import WebClient

channel = os.environ["SLACK_CHANNEL"]
slack_token = os.environ["SLACK_BOT_TOKEN"]

client = WebClient(token=slack_token)

blocks = [
    {'type': 'section', 'text': {'type': 'mrkdwn', 'text': 'Bullet list:'}}, 
    {'type': 'section', 'text': {'type': 'mrkdwn', 'text': '• `[email protected]`\n• `[email protected]`'}}
]

client.chat_postMessage(
    channel=channel, blocks=blocks
)

Expected result:

Hi @shuvaevv, thanks for sharing this, and we apologize for the inconvenience the iOS app has caused you.

Indeed, it does seem to be a bug on the iOS client app side, and it certainly needs to be resolved in its future releases. However, I am unable to tell when the fix will be delivered to you.

Therefore, as a workaround for this issue, I would suggest utilizing rich text blocks instead. Representing the list of items using the rich text blocks should work more reliably with any of the client apps.

blocks = [
    {
        "type": "rich_text",
        "elements": [
            {
                "type": "rich_text_section",
                "elements": [{"type": "text", "text": "Bullet list:"}],
            },
            {
                "type": "rich_text_list",
                "style": "bullet",
                "elements": [
                    {
                        "type": "rich_text_section",
                        "elements": [
                            {
                                "type": "text",
                                "text": "[email protected]",
                                "style": {"code": True},
                            }
                        ],
                    },
                    {
                        "type": "rich_text_section",
                        "elements": [
                            {
                                "type": "text",
                                "text": "[email protected]",
                                "style": {"code": True},
                            }
                        ],
                    },
                ],
            },
        ],
    },
]

I do realize this may require code changes on your side, but I hope you find this is helpful for the time being.
