After clicking on 'Following', the menu on the left screenshot will appear. After clicking on 'Turn off', you will see the menu from the middle screenshot. 'Turn off' sounds a bit more drastic than what it actually is: muting. Here you can choose to mute the Stories or posts of the account. And as Instagram itself states below: 'Instagram does not send notifications to people you have muted.' Isn't that nice?
If you choose 'Restrict' on the first screen, you will see the information on the right screenshot telegram data This option seems a bit more rigorous. Do you have a problem with someone? Then you can 'Restrict' this person via this option, without him or her receiving a notification. You can also find this option via the profile > the three white dots at the top right.
3. How do you manage and sort your Saves?
Do you ever save a post via the Save icon on the right under a post? I do, but I notice that 9 times out of 10 I never look back at it. Probably because it doesn't have a prominent place within your personal account. You quickly lose sight of them that way.
