Hello
Firstly, many many thanks to @robertpheller for raising this issue and for chasing up on it. I encountered the same problem around the same time. I have been following this thread for updates almost daily for the last half year or so.
Using the listed replacement file fixed my issue, but the BackWPup plugin incompatibility has now resurfaced with the new file (PayPal Zettle POS (version 1.6.2-izet-523-2)).
I only noticed that the POS plugin had deactivated when I realised that my stock counts were entirely out of whack, forcing a full inventory.
I specifically created this forum account to echo Robert’s interest in a scheduled update that will allow me to return to the standard plugin with automatic updates that will hopefully prevent unexpected downtime or stock desynchronisation.
Thank you both for your work on this.
