Why is the POS hanging on the processing page after the latest update?

Since the latest update. POS is regularly 'hanging' on the 'processing' page. Have to close POS to try again.

We also no longer have pictures display alongside variants in POS. We found these very useful.

We were also set up with all colour variants of a product with the same barcode. This no longer works and is extremely inconvenient.

Agree 100%. The new update really sucks. Bring back the earlier version until you get it right.
