@ByteHamster Same issue still happened in the newest version.

@Leetsong what about 1.7.3-RC7 on the Google Play beta channel (or custom build of the develop branch)?

[clixyz]

@ByteHamster Sorry, I'm in China at present. And these days around Oct. 1th, gradle/google/... is not accessible because of GFW. And thereby I cannot build the develop branch. Sorry for that.
