Since the latest update of SD and iOS I have a problem downloading/updating AIP-data. I encounter the issue both on an iPad 4 mini as well as on an iPhone 8. Both devices have the latest iOS 12.0.1 and the latest version of SD 3.10.5.134. Also, I encounter this regardless of the WLAN or internet connection used (home, two different offices and hotel).

The download of the AIP does work but is extremly slow when trying to download files via WLAN.

I tried a few combinations in order to get closer to the problem:

- Time required to download AIP-files into the PC-version of SD via a DSL-connection is as normal.
- Time required to download AIP-files into phone and tablet via LTE works normal (considering the amount of data to be loaded this is hardly a permanent solution).
- Time to download updates into other apps on the mobile devices via WLAN is normal.
- Time to load and open large e-mail attachements on the phone and the tablet via WLAN is normal (5 seconds for an 8MB file).
- Downloading AIP-files via WLAN into SD on the mobile devices takes forever (in excess of 45 mins for a 4MB-file).

I have tried to download different files in different country AIPs with the same result to exclude that the problem is with a single file.

The above applies both to my iPhone as well as my iPad so I presume the problem must be somewhere between iOS and SD as the WLAN-networks and DSL-connections seem to be fine and the download of files via LTE into SD also works as normal.

Short of deleting SD and re-installing it (which might become troublesome in case I thereafter still cannot load any AIP-date): Any thoughts appreciated.

For me, download of complete AIPs take a very very long time.
During the batch download, the progressing speed of individual files seems to grow non-linearly with the size.
A 1MB file took a few seconds, a 6 MB file took more like a minute or two.
The german AIP ENR 6 Enroute Chart Lower Airspace with 12MB didn't finish after 15 minutes. The cancel button did not work at all during that time. The device was getting warm.
Maybe it is not the download itself, but there seems to be a UI blocking operation that takes very long for bigger files during batch processing.
Downloading the above 12MB file succeeds in less than a second when done manually as an individual file.

Thanks for confirming what I am also seeing here. 

As you say, individually it seems fine so it is something in the batch process. So far, concerns have been dismissed - but hopefully the more people that report the problem it may get looked at.
