Apple iPad 6th gen

Recently bought an ipad mini 6th gen and I notice that although it seems to have a USB-C charge port, if you use a regular old USB-C to USB-A cable and wall-wart it only charges to 75%. You have to use the apple-supplied USB-C (at both ends) cable to charge to 100%. Not sure what is going on there exactly but it seems like malicious compliance.

I mean, even the supposed top software product from Apple nowadays, iPadOS, is suffering from annoying bugs. This will be the third time I have to reboot my iPad 6th gen today, the first two were because the keyboard would randomly close and not come back (if someone has a workaround for this issue, I would be grateful, it is a really annoying bug specially since it happened while I was writing a big text) [1]. Now, the app that I use for Hacker News (Octal) is broken on the dock, so the only way to switch to it is using the Expose-like screen. I already tried to force remove it from dock, however opening it again triggered the same bug. Also, force touching the icon shows a “Share (null)” (probably the cause of the bug). I know, not a big deal (making the user reboot three times in one day, however, should be a big deal). But this is for their top product for gods sake. I don’t want to even imagine how Catalina is. [1]: If this was Android I could at least force close the keyboard app. I didn’t find a way to force closing iPadOS keyboard, BTW, I tried to add and remove keyboard languages without success. Also annoying that I had to use another device to search about this issue since, you know, I had no keyboard at all.
