error sharing solutions between beta and main after update

[spmm]

I saved a solution before updating to the new dev preview.
Then updated the dev preview.
Then I shared the saved solution; my group are not able to open the shared solution if they are running main: error is ''bad solutionMetadata version''

I opened and resaved the same file after the beta update and still no luck.

Note the first saved version was not the highest scoring solution but a saved one which had not been opened or saved in the beta version.

Saved versions between beta and main have never been a problem previously.
