My Podcast Reviews collects your podcast reviews on a frequency set by your account type:
- Solo: updated weekly on the day you choose in your podcast settings
- Pro, Network, and Unlimited: updated either daily or weekly on the day you choose in your podcast settings
Thus, if you manually check a podcast app and see new reviews, then they are newer than the last time your podcast was refreshed by My Podcast Reviews.
If you wish to receive your new reviews more quickly, then please consider upgrading to a higher account level.
