Team collaboration has improved and project tracking is clearer but downtime still causes disruption
I think there are some parts of Lark that have not been translated, and sometimes there is a glitch where the product still uses Chinese words. Lark occasionally experiences downtime, and during those times, we usually use WhatsApp for communication and coordination, which can be frustrating. Regarding Lark's AI capabilities, I believe they are good in terms of governance and security. I think there is still room for improvement regarding the accuracy and reliability of Lark's AI output.

Real-time chat has boosted one-to-one messaging and user engagement in my mobile projects
The best features PubNub offers, in my opinion, are one-to-one chat, as I mentioned in my review, and the great SDK documentation which allows for easy integration that does not take much time. Setting up channels, message listeners, tracking user status to determine whether users are online or offline, and ensuring reliable message delivery are all great features. I find myself relying on all three of those features the most because the presence tracking is great, the delivery speed is superb compared to other SDKs, and the user status updates immediately pop up, which is significant. The integration is very easy, so any new developers can easily understand the integration process thanks to the clear documentation. PubNub has positively impacted my organization as I have received numerous reviews and feedback stating that the chat works much faster and cleaner, and everyone appreciates it, saying it feels powerful. After implementing PubNub, I noticed positive outcomes such as client feedback acknowledging that they enjoyed the chat features and found them much faster than in other applications, which I believe is very positive feedback for any organization.
