FOLIO runs pretty well on most major browsers. Generally when find out, fix if we can. They don't always make it to the team that can fix them. Dev teams sometimes reject the bug when Zak or John could have been patched.
Instead say only test in Chrome but generally expect it runs in most modern browsers. Perhaps this would allay concerns.
How can we route the bugs to a team that is better able to triage them. Would need to set expectations around that. Not every browser bug could be fixed.
Are hosts willing to provide some user agent data?
