Is Instagram consuming my mobile data?

Whenever my electric power is gone, I switch to mobile data. I get only 1.5GB of data to use per day. I need to manage all my Zoom, Teams calls, browsing and most of my work at least for few hours until power is back. It is very important for me to stop most of the apps consuming my mobile data.

 

	I usually switch on to Mobile data when my electric power is gone.
	I have restricted most of the apps from using my Mobile data. You can see here Instagram or LinkedIn applications are restricted.
	Here it's showing LinkedIn is not using Mobile data
	When I open LinkedIn, it does not work. This is the expected behavior from any app which is in above restricted list.
	It also shows in status that "LinkedIn can't use network"
	My current consumption is around 26MB
	When I use Instagram, it works as usual. I can browse different groups and photos.
	Even I can watch videos.
	This is the consumption after I close Instagram that is 44MB.
	I crosschecked if Instagram is accessing mobile data in any way. Image shows that mobile data if off.
	I think after some time it shows in notification that "Instagram can't use network". But by that time, it has consumed a good amount of data. Three years back, when I was in UK, I used to get 1GB per month of Mobile data to use. In such scenarios, its important to save the mobile data for critical activities.

I hope you can replicate the issue I have highlighted. If its specific to mobile handset and not with the app itself, I am not sure.

But it looks like, Instagram keeps consuming my Mobile where as other apps stops immediately and at times does not work. I might have found a potential bug in the application.

Please note, not all the screenshots are taken at the same time in sequence. I wanted to be sure before I post it online and have tested it many times.
