Do you have to download the freebies? I use my phone & can’t save everything.
The weekly freebie font and design element is just that free for seven days only, it does not get saved to your account so save it some place safe. the other freebies come and go from the free section of the website. So again save them some place safe.
I’d suggest a cloud-based storage option if you do not have or use a desktop computer. There is DropBox, Microsoft’s OneDrive, Google Drive(what ever they are calling it today?) Apple’s iCloud.
I use a computer and save to an additional hard drive. The phone is an unreliable storage device.
