Could you add delayed post of the message, in telegram this feature is common, but Viber even in 2022 can't release this "non-trivial" feature, BTW, you even can't add sync between multiple devices, why I have to make a back up of data to the google drive to involve synchronization of photos by my own, while it's completely your responsibility as a provider of such services, yuck, your app is not deservin to be installed in 2022, while there're a lot of normal messengers, such as telegram
