I have seen a lot of complaints from those who used (or is obligated to use) LINE at work, particularly the inability to retain anything in the chat for more than 7 days (except if it is saved in the Album for that chat or Keep), meaning that it's very difficult to keep track of all previous conversations and files. They said "LINE is anything but a good Chat App", and I fully concur. I recall that LINE's infrastructure wasn't built for multi-device use, and since the focus is needed for reliability, the underlying infrastructure wasn't touched or improved. There is a session at LINE Dev Day 2019 [1] that addressed this issue, though I still don't see much progress ever since [1] https://linedevday.linecorp.com/jp/2019/sessions/A1-2/ https://linedevday.linecorp.com/jp/2019/sessions/A1-2/
