I am using an iPad Mini 4 with the latest iOS and have been connecting to the RC via wifi.  Before installing 4.1.18 I never had a problem with video disconnects or video lag but after updating to the newest version of GO 4 disconnects and lags occur frequently.  

Just wondering if others running iOS and connecting to the RC via wifi are experiencing this problem?

(I have OTG cables but have not used them in the past because DJI says they have not been tested and I really did not need them.  Looks like I might have to go that route.)

Any message from your app? What is the system of your IOS? Please try to clean up the cache files and memories of your device.

4.1.18 is not working properly. I have downgraded to 4.1.15 OTG and WiFi is fine again (Xperia Z3 and Z5)

I am running iOS 11.1.2 on my iPad Mini 4.   Only message from the app is when video disconnects.  When this happens I still have control of the Spark.  Will try cleaning memory and cache.  I never had this problem before updating to GO 4 4.1.18 and always connected to RC using wifi.
