移动端iDEAL支付无法被PayPal捕获问题求助

已在PayPal开发者平台提交支持工单，但开发者无法定位问题，特此求助。

问题核心 #

网站使用PayPal处理iDEAL支付时，桌面端支付流程完全正常，但iPhone等移动端支付后款项无法被捕获，更换多台移动设备测试问题依旧。

支付流程对比 #

桌面端流程 #

• 选择银行后跳转至银行支付页面，扫码完成支付后返回网站
• 交易数据存入数据库，页面显示成功提示
• 款项从银行账户扣除并进入PayPal账户，支付已成功捕获

移动端流程 #

• 选择银行后跳转至银行APP完成支付，之后跳转至PayPal自带的“感谢页面”
• 款项从银行账户扣除，但未进入PayPal账户，疑似被自动退款，支付未被捕获

沙箱环境测试结果 #

沙箱环境下问题完全复现：桌面端支付可正常捕获，移动端无法执行捕获操作。

API调用记录分析 #

查看PayPal开发者控制台的API调用记录：

• 移动端仅触发了订单创建请求，未执行捕获操作
• 桌面端完整执行了订单创建与捕获的全流程
