@hazardwarning My main access to Dropbox is via the internet. Only my no 2 phone, the Android Nokia 7.1 has a Dropbox app.
As I used to use a Windows mobile phone, I have retained the 15 GB available for the OneDrive Camera Roll and was able to retain the 15 GB bonus after the free tier of OD was reduced to 5GB.
Thru my ISP, I have a “free” 200 GB on top of that 30 GB and I pay $1.49 a month for 50 GB of iCloud space.
