Hi
yanto_kiros Thank you for your asking. I just checked my device on the same firmware version and the same Instagram version. Kindly try some stay-at-home troubleshooting tips below:
1. Please try to adjust your navigation bar settings
Settings>Display>Navigation
2. Settings>App & notifications>All apps>Instagram>Storage & memory>Clear storage/clear cache>force stop>uninstall>re-install
3. Also, please try "the Factory Reset"
Settings>System>Reset options>Erase all data(factory reset)
Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
