A grade A implementation would keep a local state that syncs to the server, indicates a sync is in progress, possibly stacks changes to reduce latency if there are a lot of changes + a slow connection and, to a user, gives me utmost confidence that I’m not going to lose data.
Now my presence is to use this grade A type of implementation because I like very solid software and I’ve done it so many times now that I can bang it out in a coding interview. Or explain it to a team so they can implement it.
But your average app is like a grade D. Even Instagram or Snapchat where I’m never too sure if my stories are going to be in order if my connection fails or even though it lets me cancel an upload, if I do it slightly too late the app fails to cancel because it can’t keep track of its own state through a state transition.
So for 99% of apps, I want them to put a redundant toast. I do not believe they can build solid software with proper state management. At least the redundant toast lets me know it did go through. A lack of toast doesn’t mean it went through because some people barely can implement error handling.
Even with your description of a gradee A webapp that uses local state management effectively + shows syncing + queues with stacking + connectivity detection and exponential retries etc. I still feel like toasts can be useful to indicate to the user when are not in the "normal" state. I feel like especially mobile apps fail horribly at this, it is very normal to walk around a city and end up in dead spots. Having a clear indication from the device that we are longer in Kansas can be very useful. IMO toasts that plop up for successfull actions are often quite useless and redundant.
