Icons missing in Office 365 portal

Issue: We were using Office 365 Enterprise E5 Trial. Later got Office 365 Enterprise E3. Once the E5 Trial was expired, the icons got disappeared. Specifically, Word, Excel, One Drive and SharePoint. Tested on IE and Chrome browsers and with peers computers and all the same. Surprisingly this happened to all users.

They even got disappeared from my apps page also https://portal.office.com/myapps

Want to get them back....?

Solution: Surprisingly the solution is in SharePoint admin center.

Please go to SharePoint admin center >> settings >> Show or hide options to make sure OneDrive for Business and sites are selected as Show.

Hooray..........They all are back.
