Thanks, my friend! It looks like an issue source is a MS middle-ware component to connect to OneDrive. I just call standard API from "Speech Shooper", nothing more!
P.S. Just tried to reproduce with fresh install - no issues found
Looks like it's a French related only
bug (I connected to my main live account from test handset without any issue)
, could you please - just for the testing purposes - try to link another - le me say, a brand new - live account?
