If the client have a complex flexilayout, they may receive the "Not enough memory" error when trying to match it:
Please check what is the number of surviving hypotheses, is it set to 5 for each element. In this case FlexiLayout Studio may generate too many variants and runs out of memory.
To avoid such situation please try to reduce number of surviving hypotheses. Also it is recommended to revise the FlexiLayout Studio project's architecture to avoid branching of the hypotheses tree.
