Take a look at the network tab of the developer tools of your browser, it will all be there.
Bug reports on any software
When a bug tracker is inside the exclusive walled-gardens of MS Github or Gitlab.com, and you cannot or will not enter, where do you file your bug report? Here, of course. This is a refuge where you can report bugs that are otherwise unreportable due to technical or ethical constraints.
⚠of course there are no guarantees it will be seen by anyone relevant. Hopefully some kind souls will volunteer to proxy the reports.
Honestly if you're worrying down to the single megabyte in 2024, you're the minority. I'm aware that internet on oil rigs, airplanes, and boats is prohibitively expensive like this. But otherwise, it's a big giant don't care. If you're in that situation where it does matter, many apps, browsers, and OS's have features for bandwidth limiting and caching that can help.
Price in 2024: 10¢/mb.
BTW, the planet is cooking in 2024 and some people care about that.
Your consumption of 1MB or 50MB of data does ZERO to prevent the planet cooking.
Being on a plan that charges you $100+/GB is also a ratified case that means you're on a special internet connection and these issues should be resolved on your end so your whole system benefits from caching and data saving. If you're on a stupid plan like that because you choose to be, you're just a troll.
