Accessibility and usability barriers 

The following barriers were identified in a July 2024 evaluation. This is not a comprehensive list of barriers. Our team evaluates common user flows, looking for patterns of barriers. We do not evaluate the entire application.

Screen reader barriers limit access for individuals using screen readers, such as people who are blind or who have a learning disability

Some images, such as the profile icon, lack alternative text.  

The toolbar is hard to access via screen reader. If screen reader users want to access the toolbar, they have to close this window first, however, this ‘close’ icon can not be accessed all the time. Users are unable to access the toolbar directly.

An interface with a tool bar next to a window with a close icon. See caption for details.

Figure 1: Screen readers are not able to access the toolbar unless they close a window, and the close icon is not always able to be accessed.

Keyboard navigation barriers may limit access for people with motor disabilities

Users can not access the toolbars via keyboard. And many items do not have keyboard focus indicators so that users do not know where they are. 

Magnification and reflow barriers may limit access for people with low vision

At 200% and higher magnification, some content is not available. By 250%, content is cropped. WCAG 2.1 AA standards require websites and apps to function to at least 400% magnification.

An interface with a main panel with a smaller panel over it which covers the content below. See caption for details.

Figure 2: The content in the main panel becomes cropped at 250% magnification.
