“sorry, just realized, that connecting to sharepoint from small devices is again possible if you start with a live account and add sharepoint later ...
“As OneNote for iOs and Android was already able to connect to sharepoint servers, but seems to have lost this ability during the latest update cycle I very much doubt a technical reason.
Please readd the feature asap at least for "small devices". If it is a marketing thing requiring the user to buy a pro license so be it. But dropping a functionality without prior announcement really is bad taste,
PS: Please accept my apologies for this rant, but we are using OneNote for e-portfolios hosted on our Office365 tenant and losing available services without notification is a big issue for IT, teaching staff and students!”
