I was having some issues with it a year or so ago so I went back to 1.8.9.. But are the issues not ironed out by now? If not, what’s the problem?

Just give it another go!
Some board packages now specify IDE 2.x as a prerequisite e.g. :
From GitHub - stm32duino/Arduino_Core_STM32: STM32 core support for Arduino :
Warning
Since core release 2.8.0, only Arduino IDE 2 is supported.
The main problems I had with IDE 2.x were in the area of serial monitor/serial plotter and the only reason for swapping between the two IDEs. Copy and paste of large amounts of data from the serial monitor has now aparently been addressed in the latest version.
The somewhat erratic code completion and "hover to drill down to variable
definition" functions in IDE 2.x are good when they work, usually best for small programs, and one of the reasons I use Sloeber/eclipse less frequently now.
We don't know which issues you had. These are the closed issues: https://github.com/arduino/arduino-ide/issues?q=is%3Aissue%20state%3Aclosed
And these are the bugs or feature requests: https://github.com/arduino/arduino-ide/issues
Either learn to live with them (most people do) 
Or stick to 1.x (I think 1.8.19 would be preferred).
