I just loaded AD Beta 2.3.0.2139. I then tried to open a recent drawing I started in AD Beta 2.3.0.2096. I get a message:
I don't know if the error was in 2.3.0.2096 or is in 2.3.0.2139. I've tried it a few times. I get the same result.
I tried the next few documents in the Open Recent. Same results on all. Including one from a Beta version before 2.3.0.2096.
Run on a 27" Mac running Sonoma.
