Sending medias is super fragile

Sometimes I try to send a media while I'm on 5G. I know the Rust SDK should enqueue the media in the send queue, but it seems the media sending gets stuck before this step, with the spinning loader still showing up. It seems to happen quite frequently, so maybe I can upload a rageshake for this later.

Worse: if I click "cancel" to abort the stuck sending, any attempt at re-sending by pressing "send" again causes absolutely no changes or no progress: nothing happens. In some other cases, I get an immediate error message, independently of the number of times I abort and retry. This means I can't re-send the media, and I may lose both the caption I've entered as well as the photo picture/video if I just recorded it. This has happened to me quite a few times, and it is quite frustrating.
