Live view Phoenix.LiveView sessions require string keys

I have the warning Phoenix.LiveView sessions require string keys, got: :user or :xxx
with version 0.5.0 and phoenix 1.4.11

when I try to replace atoms with string keys it does not work anymore

I tried to upgrade phoenix to latest and phoenix liveview to 0.8 but then The app does not compile anymore

it is just a warning, not an error, and the app works ok excepts sometimes the liveview get stucked

I suppose I should upgrade to 0.8 but looks like there are some breaking changes

thanks for any help
