I’m OK with these being under one report at the moment.
I agree with @gcwarbler that these are a lot of observations to be importing in one batch. I try to keep it to 10-20 or so at a time. The app supports the import of hundreds of photos, so I think it shouldn’t be failing like this, but I suspect very few people are importing this many observation at once.
I agree the app has some upload issues, but I’ll also note that in the video you only have two bars of Wifi, which to me signals the connection isn’t that strong and may be going in and out.
It looks like you’re making hundreds of observations of one species, like each individual alfalfa in one day? Frankly, iNat is not designed for recording abundance like this. May I ask what your goal is by doing this? I’d recommend just making far fewer observations, maybe a representative or two of the species of interest.
