Hey there, andrew-L. Thanks for trying the troubleshooting steps presented by my colleague.

Since this is now how the product functions, your best workaround will be to make use of a mouse when necessary.
Changes like this are generally discussed in our What's New in QBO Archives. The most recent article published there is for July 2020, and it doesn't mention anything about this update. There should be one released for August as well. I recommend keeping an eye out for that.
