Connect is printing queue items multiple times

Recently, since maybe about 2/3/4 weeks(i dont print very regularly), i observe that connect randomly starts print jobs another time after they are finished.

It seems to happen mainly when I upload multiple items onto the device - either with the web form on the "printer files" tab or directly via slicer.

I first thought i made have made a mistake,. but it's now the third time that the quese isn't working properly and that instead of the next item in the queue fomr some reason the just finshed item gets printed again.

I also in the meantime double check the queue after each upload, but it always looks good - until i take out another finished object out of the printer, set it to ready again, and get to see that it isn't printing the next expected object but the last one again.

Does anyone observe a similar behaviour?

maybe this is the same as described here and seems to be known since quite a while but noone from Prusa seems to be willing to answer 🙁

RE: Connect is printing queue items multiple times

i have the same issue. when uploading to prusa connect from the linux version of prusaslicer, stuff ends up in the queue multiple times, and sometimes at some time in the future, stuff that was printed before the current print gets schedules for the future again. it is really weird, as i could swear that slicers upload function told me it is going to be slot #2 in the queue when i uploaded it.

RE: Connect is printing queue items multiple times

I also report this issue, when sending a print file to connect. I only use connect to send the files to the printer, and when I send one file to connect,

it appears twice in the printing queue. 
When I do not remember this issue and set the printer ready, after finishing another job, the old file is repeated, instead of the new uploaded one.

Maybe it's also possible that the issue is addressed to the firmware (6.4.0 RC)

Prusa Slicer 2.9.3

RE: Connect is printing queue items multiple times

I have been suffering from the same issue for a couple of weeks now as well, I am currently running windows and a wired connection to my printer, and every time I send a print to it, even off the in-app slicer it will queue it twice. Hoping the fix it as it is a major inconvenience.
