I was helping to test ElasticSearch components for 7.1, specifically https://customer.liferay.com/documentation/7.1/deploy/-/official_documentation/deployment/installing-x-pack-monitoring#monitoring-in-product
The documentation reads:
Open the Add menu on a page and choose Applications
However, in 7.1, we changed the term Applications to Widgets. Please make the update to reflect the new terminology and potentially reduce confusion among users who may not be familiar with our previous terminology.
I haven't checked other pages, but it is likely those have been affected too.
