Using eM Client V9.3.6041 droid app
I renamed a parent Gmail label via the eM Client desktop app, which then synced that label change to Gmail online the same.
Then closed and reopened the eM CIient mobile app and the label change synced to the mobile app, but the emails i had in that label were no longer showing ?.
So went to the Gmail mobile app and all the emails were showing in the updated label name, but just not in the eM Client mobile app.
So then cleared the cache in the eM CIient app, but that made no difference.
So next went to All Mail in the eM Client mobile app, and the emails were all showing there but still had the old parent label name in all the messages ?
So changed the message labels via the tag option, to the new updated parent label name, and now all the emails are showing again in the new updated renamed eM CIient parent label.
