Thanks, Cobra.

Follow the instructions he set forth and we'll get to the bottom of this.

I've been seeing the large missing rectangles of radar data as well. They are often within the regional radar area and are always rectangular in shape with the long axis running East-West. Not sure where in the stream of data these blocks are getting dropped (ground source, stratux, ifly on Android, etc). As of my flight yesterday, I was only getting 1/3 to 1/2 of the radar updates to fill in correctly. So these missing blocks are happening more often than not. They're easy to see when the radar has a large area of active returns, but will completely miss entire storm cells that aren't embedded. I had between 2 and 4 ground towers in sight the entire time so I doubt this is a signal/connectivity problem from the ground to the receiver. Please help.

Have you done this yet?  If not, help them help you:

The only way to really know for sure is to capture an ADSB log when the behavior is occurring (Menu > Setup > ADS/B > Options > Enable ADSB Logging (check)), then send that logfile in for the AP folks to look at.  

There's a lot on their plate right now, so unless several people report a similar problem this may not bubble up high enough on the priority list to get much attention, but it boils down to:  Send in the log and there's a chance for an answer.  Don't send in the log, and all you're going to get is shrugs and speculation.

I was doing this part from your previous comment, "so unless several people report a similar problem." I am, in fact, reporting a similar (same) problem.

I found this thread after experiencing the issue in flight. So no, I wasn't able to time travel backwards to pull the ADSB logs per your earlier suggestion.

Further, I don't expect your "help them help you" snarky response to a commercial software product with a paid subscription. I would expect that on my github account, but not here. I pay more money for this software product every year than all other software I use combined. That comes with certain expectations about how bugs are handled. A polite recommendation to grab a log file next time it occurs would be fine, though considering the very busy cockpit environment that had both pilots working feverishly on planning diversion alternates to changing weather conditions in busy airspace makes getting a log file pretty low on the priority list. Lastly, missing radar chunks (data blocks) is a common ADSB issue across several products when the software isn't correctly merging the data frames from multiple gound site broadcasts. Though I can't know whether this is a stratux software bug or an ifly bug, the development team here should definitely recognize the signature from the screenshots provided.

Wasn't meant to be snarky.  Was simply meant to point out that if there's a real problem, they'll need data to solve it.  Had you included a comment in your original post that "I see the info on how to grab a log file, so I'll try to do that if I see it happen again", I woudn't have reiterated it.
