Immich and iPhone Storage
When experimenting with the Immich iPhone app I found it impossible to upload beyond 15,000 images and I supposed that it was because the phone timed out before it had checked all the previous files before moving on to the last four thousand images. In reality the problem is that Immich downloads the media from iCloud and leaves it on the phone. The result is that if you have one hundred gigabytes of photos on iCloud you need one hundred gigabytes of storage ony your phone.
