Oxford Learner dictionary doesn't understand words when they are capitalized, so if you try searching "Learn" you will get "Word not found in the dictionary", but it works fine with "learn". I think the query is wrong, when I search "Learn" on the site it redirects to https://www.oxfordlearnersdictionaries.com/definition/english/learn?q=Learn, but the extension opens the page https://www.oxfordlearnersdictionaries.com/definition/english/Learn
Is there a way to fix this?
Update: I checked search on the site and it seems to send two requests
Both seem to redirect to the correct page.
