Turn on the Instagram* app, and it's lagging. The phone alerts you about a lack of memory. What's the problem? Most likely, this means that cached data has accumulated in the app.
What is cache in Instagram*?
Cache, or cache, is a folder where temporary data necessary for the app's quick operation is stored. This folder may contain passwords, text, and multimedia files – everything that helps Instagram* load content. However, the cache stores all data, not only Instagram*: search queries, multimedia, web addresses, and more — everything that speeds up the gadget's performance.

Why clean the cache?
Despite the cache being quite useful, it can interfere with the device's operation. Data gradually accumulates, becomes outdated, and irrelevant, new data and files are added, and the device's memory becomes increasingly less... This leads to the gadget working slower and slower. This is something you can and should do something about! Namely – clean the cache.
Remember that when cleaning cached data, temporary files that apps usually save to avoid reloading, as well as logins and passwords, are deleted. Therefore, first, make sure you remember your password or know how to recover it, and then clean the cache.

- Open settings and go to the "General" section.
- Select "iPhone Storage."
- In the list of apps, choose Instagram*.
- Click "Delete App" and then download it again.
