Version 2.6.1 (1217)
After the latest update I can’t interpolate, it says: “Alignment zones not set correctly in all masters”
The alignments zones are the same in all 4 masters and all overshoots are in the zones. It wasn’t a problem with the last Glyphs version.
I have fixed that and will update in a minute.
It happens again on my Version 2.6.4 (1286)
All alignment zones in all masters must be the same number and order (order of positive top and negative bottom zones). What do your zones look like in all masters?
