I'm not expecting a reply from Foolography on this as it appears that there is no longer any support for this product but hopefully someone on the interwebs may be able to help. Using the Unleashed, with current firmware, on my Sony A7RV and the latest version of the iPhone app, my interval during Holy Grail Timelapses actually changes about 1/3 into the sequence of photos for no apparent reason. The interval should remain the same throughout. This has happened every time since these updates with different settings. I took a number of Holy Grail Timelapses about 6 months ago with previous firmware etc. and the interval remained constant throughout. As it should.
Just putting this out there in the hope that someone may have a suggestion for a fix or work around. We live in hope...
