Shouldn’t it be blocking? I mean, shouldn’t we display a splash screen until the process is complete? Or what’s the plan here? Currently, every time I open the POS for the first time, it shows an empty list of products.

[samiuelson]

Good question. The plan is to make the incremental sync non-blocking in general. However, in the next PR, I'm going to add a check if the full sync is required, which will handle cases like POS opened for the first time (empty local catalog). In case the full sync was never performed before, or the catalog is empty, the full sync will be required and will block an access to POS.

LGTM! I left one non-blocking question
