What’s New

Version 5.3.4

Update Highlights 
• Sync Improvements and Progress Bar: Sync logic has been optimized to improve download of data types and users can now view a sync progress bar to monitor their sync downloads.  
• Field Boundary Error Handling: Users can resolve boundary errors that prevent fields from syncing by  either editing the boundary, using the digitizer tool to fix it or deleting it. 
• Revert Field Boundary: Users can select to 'Revert Field Boundary' for a particular field. This allows the user to choose from a list of historic boundary for a particular field to use for activity collection 
Bugs Fixed 
• Issue that caused users to be logged out of Sirrus when Wi-Fi became unavailable  
• Issue that prevented yield operations from showing in the notifications pane 
• Issue that caused comma to be entered as a decimal for Seeding Rate and across the device 
• Issue that prevented Databullet data from syncing to the device 
• Issue that prevented users from completing a Management Zone operation due to Management Zone crossing an interior polygon 
• Issue that prevented users from receiving imagery for newly enrolled fields until they changed the season (year) in the Imagery Settings 
• Improvement to stability and app performance due to the addition of a sync progress bar and prioritization of sync items

Improved but not perfect

Sirrus has finally solved our issue of syncing data across to multiple devices and has minimized app crashing. The app still crashes occasionally but seems like it can not keep up with the amount of data I put in it at one time. I am still waiting on color coating fields to match technologies. Overall it is still a good app and gets what I need done.

I use the app everyday scouting fields. When the app works like it supposed to then it is great. When I am not able to receive or give data I am not able to give my farmers the information they need. If they don’t get the information then I am out of a job. Every time there is an update to fix one thing they screw up something else. This happens every year. Tech support is friendly but the developers are a joke. Don’t fix something that isn’t broke.
