My subscribers count dropped after my account expired.
FeedPress never removes your feeds if you don't ask us to. That's one of our engagements as we know that delivering an RSS feed is crucial for you and your subscribers.
If your account expires, we still deliver your feed as usual. The only difference you will notice is your subscribers count that will probably drop, as we only calculate your subscribers on a 24-hour period, while paid users have their subscribers count calculated on a 7-day period.
Once you reactive your account, the next subscribers count will automatically be based on a 7-day period again.
