HI. Is it correct? I assume if the provider is same, userId is same too, even if using different types of api. Because I can get same uid from my messagin-api and social-api (offcourse they are in same provider). But i checked it from account of myself ( = channnel's admin) only.... I will get another sim, and I'll check it more precisely.
my apologies for the inconvenience. こじ answer is correct. there were a hardcoded syntax in our lines that point bot and line login to different providers. :(
