The subscription and the SDK part can be improved. If the client is offline and the application is killed, and the user comes back again, sometimes the subscription to the channel is missed, so that needs to be improved at the SDK level. Most of the working of our application is working on it and we are happy with it, but there are some parts at the SDK level and the subscription level that we are not happy with it.

I am not sure how PubNub can be improved because our project and scenario were fulfilled by PubNub, and we did not face any challenges with any of the features, nor do I want to improve anything. As of now, I have no challenges that would make PubNub better. During development, we faced a challenge of getting very little support from PubNub team based on the cost of the products we were offered. I believe some basic support should be given for the features being used by the client after paying for it, rather than requiring separate purchases for support.
I believe PubNub can improve in terms of pricing transparency, as I previously mentioned, since that is the only thing I think should be improved because for smaller projects or startups, estimating scaling costs can be challenging. However, from a technical perspective, the platform remains stable and developer-friendly. I chose eight out of ten because there are two more points that need improvement: one is pricing transparency, and apart from pricing, I believe the community is not very large, which means it takes time to get support.
