I have the same problem. It shows them as installed under the Installed area, but they stay listed in the Updated area even if I refresh it. They work in the rest of the app, just the Add-ons screen has that quirk. (iOS, Pleco v3.2.32)
There was a bug on Android for me, too, indicating the download failed and asking me to go to pleco.com/androidfiles .
I tried a second time and everything went smoothly.
Maybe we are too many downloading at the same time ?
If refreshing doesn't help, try background-killing and reopening Pleco, or if you don't know how to do that, rebooting your phone; that should get it to reload. (problem was some bad cached data)
Maybe they're not really necessary. Then again, if there weren't any, someone might come up and ask for them.Are the stroke order diagrams in your dictionary really necessary?
We’re investigating a bug there- if you delete one of the two versions (simplified or traditional) and then exit / reopen Pleco, does that get the characters to appear normally?
Fix is up now, sorry about that. (entirely on our end, related to not having enough PUA codepoints assigned to cover the 20,000+ images Outlier is now including in each edition of their dictionary)
