Thank you for your post!
This may seem obvious, but have you tried uninstalling FileMaker Go 15 from the iPad Mini and reinstalling it? You could even go as far as restoring the device and installing FileMaker Go 15 to confirm it's not device software issue.
If you have narrowed the crash down to the EasySync process you may want to contact support for FM EasySync, if possible.
Sometimes obvious is good. Reinstalled FMGo 15.0.1 after completely deleting it and all of its data.
Reinstalled all databases and it all works.
Apologies for airing issues, although I sure would like to know what causes this type of problem
in the first place : )
I suspect if it is helpful, that this is not an installation issue since it occurred on several iPads and all of the were working correctly for weeks without re-installation. This may require some closer investigation as to why this might have happened. May have been a function of iOS updates interacting somehow with fmgo 15.0.1 on slightly older iPad hardware. If there is some aspect of corrosion in the code it will not go over well with large field deployments.
It is good that a re-,,install of fmgo successfully eliminates the hard crash but this is really a patch not a solution.
I apologize. I got the impression the crash only occurred on one device.
I have in hand, one iPad that crashes and one that does not.
I would still strongly recommend contacting any support for FM EasySync as we don't really have any experience or background knowledge of how it works. Is the following still where you are seeing the crash or do you have further information?
