Updated to last version of Sketch 50.2, CraftManager v1.0.64 and Craft Sync to v2.3.75.
Sync is painfully slow with more than 2 min to upload a single simple Artboard with Sync. It very frustrating because it's also preventing me to continue to work on sketch while it's updating. (Sketch is frozen with a spinner cursor).
Also did the test when the Sketch file doesn't contain any symbol the upload time is "normal." But very slow on my original project which includes more than 100 Symbols.
Can't use Craft in this context. So I tried to export the board manually via sketch and drag and drop the image in Invision, but now Invision tells me that the file is too big (@2x png for transparency).
Do you any tips or ideas how I can speed up the upload process?
