A Microsoft file hosting and synchronization service.
I've been having the same problem here (Brazil) for a few months. I've already opened a few tickets, but I haven't received any satisfactory answers.
I noticed that it's not really a bug, but rather an intentional change to reduce the traffic load on Microsoft's servers. I say this because I found reports from users in February/2024 and the "problem" has been gradually advancing for users over the past few months. For me, it happened in April/2024. It's as if they were advancing slowly and silently so as not to generate an avalanche of tickets.
I'll need to migrate to another cloud tool, does anyone recommend one? Dropbox, Google Drive... something else?
