Cons

Con Long list of paid-only features
Free features are pretty basic. It seems like all the new development goes into paid-only features. Paid features include sharing and saving options, alerts, backup, support or integrations with collaborative tools.

Con No push notifications
Among the most requested features for Feedly is push notification support. The feature was officially requested in 2011 and currently has over 600 votes on Feedly's Uservoice.
Con Log-in is buggy
Logging in can sometimes cause Feedly to struggle. It can become unresponsive and force close.
Con The layout isn't like Google's original or Inoreader's of which is much easier to browse and read quickly
Con Inline adds
Free version puts adds in your feeds
Con No keyword filtering
Feedly has no ability to filter a feed by keyword like a lot of other RSS readers do.

Con No offline support
There is no offline support with the official client.
Con Forces external account to log in
Users are forced to use Twitter, Facebook, Google, or Microsoft login credentials.
Con Steals page views
Feedly has had issues multiple times with hijacking page views from original publishers. See:
Con Organization/sorting features lacking
There is no ability to sort feeds within a folder, and moving feeds between folders is difficult with lots of content.
Con Slow interface

Con Ads in free version
Ads appear in both mobile apps and the web version.
Con Limits free users
While Inoreader's basic functions are still available for free users, many of the options involving customization and search options are limited to paying users.
Con Can't have unread items older than a month
If you don't read items older than 1 month they are automatically marked as read, with no possibility to "unread" them.
Con No sub folders
You can't create sub folders. This makes it a bit harder to organize saved content.
Con Price change / Feature capping instituted
In February 2019 Inoreader announced that the "Professional" plan will be capped (big change from unlimited filters to just 30!):
Based on our observations, the new premium feature limits on the “Pro” plan are as follows:
10 Rules - *** Increased to 30 Rules after Inoreader evaluated feedback from their users.
30 Active Searches
100 Boosted Feeds
30 Social media feeds per service (Facebook, Twitter, VKontakte).
These limitations will be applied to your account at the start of your next subscription period. All features that you use above the new limits will be deactivated, and only those that were created earliest chronologically will remain (For e.g. your earliest 10 Rules created).
Con Mail2Tags is buggy
Only a small amount of e-mails looks OK. Most e-mails are unreadable.
Con Uses Ram when it is not active (stays in memory)
