Why don't the WeChat avatar and nickname of students in the H5 Online Store get updated after they click the synchronization button? 中文 Due to WeChat restrictions, there is a 5-hour delay after a learner changes their WeChat avatar or nickname. Therefore, within these 5 hours, elink cannot obtain the learner's latest WeChat avatar and nickname (similar to other platforms). In this case, learners are advised to wait for a few hours and try again.
