switched my 2nd sd card partition to fat32. any downside?

[catchingup]

I have been getting random mount problems in link2sd with ext4 on the 2nd external sdcard partition, so I decided to partition my sdcard with 2 primary fat32's.

Any downside to running fat32 when linking apps in link2sd?

I'm not sure there is a down side so to speak but I would have just used ext2 I mean for a mobile device that is more than a sufficient file system. I like to use it because unlike ext3 and 4 it does not have a journal system so it doesn't need the resources that they do. The reason I recommend the ext2 is because it is a native file system for Android. I'm not sure if you remove your card and put it in your computer or if you hook up the device via a cable to the computer but having the ability to view the external partition and edit it could lead to issues. Since Windows does not see ext* partitions it does not allow the user to access it and chance messing something up. Anyway just my suggestion.

As far as any issues running fat32 extended partition with Link2SD I have not personally heard of any.

The only downside I know of using FAT for the second partition is for linking app data. If you wish to use the paid version (Link2SD Plus) which allows for linking data in addition to the app itself, your second partition must be a non-FAT format or the data link won't work. It's explained in the app details in the Play store.
