Update: the second taped spool did let the filament release from the tape and the tape stayed on the cardboard center spool. I was ready with my cutters, just in case.
So, 50% error rate here.
Later, I finished an older roll that had no problem, but that was because the end of the filament was inserted into a hole and easily pulled out, Much better! I suspect that they changed suppliers.
My P1S/AMS combo flawlessly finished off one spool and switched over to another spool of the same color while I was sleeping last night (as it should). The spool that ran out had the new version of tape applied to the filament end, with only about 10 mm capturing the end, instead of the approx. 20mm on the offending spools. This filament was purchased Mar. 16, so maybe the older filament inventories have mostly been sold off (but I’m sure that there are some less-ordered popular types/colors still lurking to be bought). It’s remarkable that this thread is nearly 2-years-old.

What about simple running “tail” under the rest of filament? Polish manufacturer Rosa3D does this with it’s refills (here mounted on Bambu spool on adapter) - absolutely zero issues with AMS and with just dryer (Sunlu S2):
Edit; Ok as always it might have issues with rewinding when little to nothing is on the spool but it’s edge case

Well, that is arguably less secure than having e.g. a 45 degree end bent into the cardboard ring. Good idea though!
This continues to ruin prints for me to this day, 2 years after the first post in this thread. Remarkable how such a company can produce so good printers, yet have so little interest in fixing this.
Clearly my main source of print fails. Outrageous.

One of my petg hf spools reached the end today and revealed this mini white tape holding the end on. I haven’t seen this method before. It covers about 6mm of the tape end and actually wraps around inside the cardboard. This spool was purchased in the last 30 days. It released perfectly.
