"opening file failed"
Recently, I have been unable to consistently reopen/share saved files.
1) I am able to save and reopen the following file but it does not open for others properly
Tested on a mac, geogebra/3d/ opens but fails to load tile and gives the message "opening file failed"
2) this 2nd file was saved by me this morning and fails to open now even for myself.
Any ideas suggestions?
I am using chrome Version 89.0.4389.114 (Official Build) (64-bit) on windows 10.
