no conversion needed - V14 files should open in Go15.
- check for startup scripts, triggers, etc.
-> the file is local on Your iOS device?
When opening a SeedCode Calendar for the first time in 15 it didn't work. It appeared that Go15 didn't support web viewer writing to the iOS temp file. "It looks like FileMaker has changed something in the web viewer in Go 15. Unfortunately, the web viewer in Go 15 cannot dynamically read from files stored in Go's temp directory, which DayBack does to render and interact with the calendar." (this is now fixed by SC) could it be that your solution attempts this?
there's something missing. Using a verbose log I do not face any relevant problem, but layout appears with no button s and no visible controls.
I have tried opening a different really small local file.
It opens but I have different color rendering (see images). This is a minor issue but makes me think ...
(image1 is opened using FMGO14, image2 is opened using FMGO15)
