I have a Dropbox basic (free) account that I share with my spouse and we use on more than 3 devices. When I received the letter from Dropbox saying the limit was 3 but current devices were grandfathered in I thought I’d see how many devices I had. I found two old computers and two old phones and removed them both. A few days later I noticed on my MacBook Pro that the Dropbox icon was greyed out. After further investigation, two Dropbox chat sessions, and about 8 emails back and forth from Dropbox, I learned that Dropbox had not only dropped my MacBookPro, they had said it was NEVER linked and refused to add in it. My suspicion is that my old computer had only the same name (MacBookPro2009) from my current computer (MacBookPro2012) and that they had a technical glitch. The other option is they are dishonest and doing this on purpose. So the choices are: (1) technical glitch and Dropbox unaware it exists (very scary since they are supposed to protect our data), (2) technical glitch and Dropbox is unwilling to fix it which shows really poor customer support, or (3) they are intentionally creating these technical glitches so people will be forced to pony up the $9.99 a month for 1 TB when they’d much rather pay less for less storage. In my case I have a free account that is shared with several paid accounts and $120 is WAY too much for what Dropbox provides that I already can get with iCloud, OneDrive, and Google Drive. People for years have been telling Dropbox to lower their plans and they’d pay. Instead of listening to their Basic customers,,,they basically screwed them.
