How is connecting a blue tooth mouse to an iPad any different than connecting to a computer? Especially with iPad OS 26?
Downloading 15 different paid or free-with-in-app-purchases or free-with-ads apps to see which one actually does what it's supposed to do is one of those workarounds. I've learned how to do it and done it a bunch of times and I don't really like it. I much prefer the macOS/Windows/Linux workflow where there's typically some established, community run and trustworthy FOSS software to do whatever conversion you need.
