Infuse Pro 家庭共享的问题

楼主组织了 Infuse Pro 的车队，在美区购买了终身订阅，目前有 4 位队友，队友在加入「家庭共享」后，他们用自己的设备在楼主的「已购」里面下载了 Infuse Pro 后，使用「恢复购买」无法恢复 Pro 模式。

然后尝试使用了 Trakt.tv 帐号的模式，有几个小伙伴在登录了 Trakt.tv 帐号后是可以恢复 Pro 模式的，但有几台设备无法恢复，所以想请教下各位大佬，Trakt.tv 这个模式是不是有设备数量的限制？

在查阅过官网论坛的说明后，开发者也明确表示，终身订阅作为内购，应该是支持「家庭共享」的。下面是官网的原文：

Family Sharing

Family Sharing is supported for both in-app purchases and subscriptions. Learn more about Family Sharing 623

Tips for Family Sharing (iOS 14.2 and later)

Family member(s) have been added to Family Sharing 149 (with Purchase Sharing enabled)
For monthly/yearly subscriptions, ensure sharing has been enabled in the Infuse subscription page (App Store > Subscriptions > Infuse)
Tap the Restore button on the purchase prompt (if it appears)
Note: In some cases it may be necessary to delete and re-download the app from the main family member’s list of Purchased apps in the App Store.

Alternative option for Family Sharing via Trakt

Family member(s) have been added to Family Sharing 149 (not required if accounts are in different App Store regions)
Log in to Trakt on the purchaser’s device, and then the same Trakt account on other devices

有没有小伙伴遇到过类似的问题，想请教下，感谢。
