Narrative:

I downloaded [efb] jepppro version 3.0.2. I had also completed the 'cqdl' for the new version prior to downloading. All seemed normal with the app although it appeared that on landing slowing through 80 KTS the taxi chart would automatically come in the amm (airport moving map) mode instead of the chart mode. Arriving in ewr on the 5th on flight ##### I noticed during the landing rollout that the taxi chart was in amm mode and the screen was blank. I switched it to chart mode; which worked normally. I assumed it was just a glitch and forgot about it. The next night we landed in ewr again on flight ##### at night. The taxi chart again came up in amm mode and the screen was blank. Now I was paying attention a bit more. After thinking about this for a day; I have some concerns.1. it appears as though the taxi chart now defaults to the amm mode on landing rollout. This default requires an action by the pilot at a critical time to get the info needed. I also find the amm mode a little disorienting at this point; as I don't really know what I'm looking at. Again; a huge threat at a critical time in the flight.2. unfortunately; this chart has very little information (no frequencies; light information; runway lengths etc.) and does not meet the needs of a crew trying to ascertain their position immediately. It may be that in the future; the amm chart will have the needed information but it is completely inadequate now.3. the amm chart on my ipad seems to work normally on other airports but not for ewr. This is obviously a major problem when it defaults to amm.4. there doesn't seem to be a choice in jepppro settings for the pilot to select amm or chart for the taxi chart. Why would this not be a pilot selectable setting?in conclusion; there are at least four threats here. The chart defaulting to a taxi chart with inadequate information; a chart we are unfamiliar with; apparent blanking at some airports (at least on my ipad); and the pilot having to fiddle with the ipad at a critical time during the landing roll.
