Solutions

1. Inspect live DOM and update the 'div.bottom button.submit' selector to current markup
2. Ensure the editor still has focus before looking for the submit button
3. Wait for the button element with a timeout instead of immediate query
4. Verify account/comment permissions in a normal browser session

Example fix

// before
submitButton, err := page.Element("div.bottom button.submit")
// after
submitButton, err := page.Element("div.bottom button.submit", rod.El{"timeout": 5 * time.Second}) // and confirm selector against current DOM

// 提交前确认按钮存在于当前 DOM（页面稳定后）
page.MustWaitStable()
_ = page.MustElement("div.bottom button.submit")

err := svc.PostComment(ctx, feedID, content)
if err != nil && strings.Contains(err.Error(), "未找到提交按钮") {
    // 检查是否改版/编辑器收起，人工核对后更新选择器
    log.Warnf("提交按钮未找到: %v", err)
}

When it happens

Trigger: The submit button is absent because the editor closed, the XHS UI renamed/removed button.submit, or the page rendered an alternate layout (mobile/AB test) without that class.

Common situations: XHS frontend redesign changing button classes; editor auto-collapsed after typing due to lost focus; account-restricted state hiding the submit control; half-loaded page.
