Dropbox app not recognizing external SSD for backup on Mac computer

RP15

I am running MacBook pro m3 max with sequoia 15.3.1 and want to backup a Samsung T7 external SSD formatted APFS encrypted, has 1 file in it 50MB. Dropbox will not recognize the drive, I have tried reformatting, quitting dropbox and signing out of dropbox. Any help welcome as otherwise the backup feature is next to useless for me.

Hey @RP15, thanks for your post today.

If your external drive is encrypted APFS, I'm afraid that it's not supported.

On Mac computers you can backup HFS+, APFS, exFAT and FAT32 formatted drives.

I hope this clarifies things, but if you still have questions, don't hesitate to let me know.

Thanks.
