You may need to wait a few days for the sdk to refresh the homeserver capabilities.

I just noticed the developer setting for simplified sliding sync is turned on even though the client is still using the sliding sync proxy. I didn't touch the setting on the stable play store version.

It's possible #3458 in 0.6.1 enabled it by default even on existing sessions before homeserver capabilities were refreshed which blocks the migration banner from ever showing up

Fixed in 0.6.5
