I’m a regular user on a Discourse forum, and I usually have many tabs open with many discussions. The problem is what when Discourse finds an update, I get the same popup in every tab. Clicking Refresh in one tab doesn’t refresh all other tabs (at least in Firefox 87/macOS), so the forum keeps asking me the same question ad nauseam.
The second problem is that, honestly, it’s a detail that I don’t care about. I know you take pride in your releases and there’s clever ServiceWorker machinery in there to update. But it’s not something that affects me to the degree of urgency that this popup has. I usually can’t even tell what changed. I don’t feel like I need to drop everything I was doing and update immediately. If these updates actually are some overdue urgent security updates, then you should say so explicitly, or even just refresh without asking.
The popup demands a decision from me, but gives me no information or context to make this decision, and no justification for presenting it as an urgent interruption.
