Sync stuck at “Synchronising Shopify data”

Hi, thanks for this great plugin.

I am using the free version of the plugin.

I was able to sync about one week before, but now it is not working anymore.

I have activated my products in Shopify and I have made sure all my Admin API Permissions are set to either Read and Write or just Read if there is no Read and write option. Also all products are in the “WP Shopify Channel”.

When trying to resync, the sync process is stalling at Synchronising Shopify data …
(Please wait, this can take up to 5 minutes depending on the size of your shop and the speed of your internet connection).

Even after 10 Minutes, nothing happens (we have about 180 products in our shop).

I see no error messages in the Browser Console.

I also deleted all shopify data with the plugin, and reconnected successful to the shop, but without any progress.

What can be the cause ?
