Kept hitting OAuth errors, switched to All Cloud Hub
Used MultCloud for a few weeks trying to manage files across google drive and onedrive. The core idea is exactly what i needed but the oauth connections kept dropping every couple of days and i had to reconnect accounts manually each time. Also felt uneasy about how credentials were being handled in the background, the privacy side was not very transparent. After looking around i switched to All Cloud Hub (allcloudhub.com). Connects the same clouds, oauth stays stable, nothing gets stored on their servers, files stay in your own accounts. Has a free plan which covered my personal setup fine. MultCloud might work for simpler one time transfers but for ongoing day to day management across multiple clouds it did not hold up reliably enough for me.
