What should we do when the filter blocks a website students need?
Report it with the address, the group and the date so the filter choice can be reviewed. In the meantime, give students another route, such as an allowed app, or ask the team about a different filter for that group. Per-website allow lists are not available yet.
Every category filter has false positives. A research site, a school board portal or an online exam can be caught by a category set up to protect younger users. The question is how quickly you can handle it.
First, confirm it is the filter and not something else. Check that the device is on the latest policy, that the network is not blocking something itself, and that the site does not rely on a pop-up, which Chrome blocks on managed devices. Test on a second device in the same group.
If it is the filter, send the address and context to support. The filtering provider can review the category, and the owner can consider a different provider on the curated list. A group with a different need can use a different filter, set at group level.
While waiting, choose a workaround that fits the lesson: put the content in a learning app on the group's list, show it on the classroom screen, or use a lesson window with an extra app. Do not switch off filtering for the whole organisation for one site.
Per-website allow lists are not available yet, so you cannot unblock a single address on your own. The team is working on finer controls. Set expectations with teachers: most sites will work, and a few will need a report. A shared form for staff to collect reports keeps requests tidy.
