We have the free version of dropbox at work. 3x computers make use of it. It's all excel files we have in the shared folders. At some point last year we discovered the files stopped syncing. Storage was full- deleted old files that were no longer necessary, then dropbox worked again. There is about 1GB of free space left.
Again, dropbox has stopped syncing out of the blue. We have a solid internet connection. I noticed some troubleshootings mentioned it could be the antivirus- we have AVG free version, but we have had it since a long time ago and dropbox has always worked up until recently.
On all 3x computers, the files show the green tick. But, let's say I make a change on X file, that change would not reflect on either of the other computers. Same if someone on the other computers made a change to X file, it wouldn't reflect on either other side either.
Any suggestions on how to fix this issue? I am pulling out my hair trying to get it to sync. We don't have an IT department and I'm the only one in the office who generally has a good knowledge about computers, but this issue I fail to understand. Any assistance and advice will be gladly appreciated.
