Limitations

Higher paid pricing: The personal 2TB plan at about $9.99/mo is more expensive than some competitors over time.
Restricted access in mainland China: Sync speed and availability are unstable, so domestic users need network solutions or local services.
Historical security incidents: There have been security events in the past, so sensitive files need additional encryption and protection.

Team file sharing and collaboration (recommended ★★★★): Team folders, share links and Paper combine well; see document collaboration platform comparison.
Contract and signing workflows (recommended ★★★★): Dropbox Sign digitizes contracting and approvals.
