(MC) Support Tip: MC2.53 hotfix to overcome upload limitation of 200 MB.
You may be aware of the app upload size limitation in Mobile Center help online that "The maximum file size that you can upload is 200 MB. " https://admhelp.microfocus.com/mobilecenter/en/latest/Content/Adding_Apps.htm#
But if your app size has to exceed the size limitation, please let us know and we may provide hotfix for it. Currently, we already have hotfix for MC2.53 in hand.
Regarding formal solution, there is already a backlog improving the uploading performance. https://softwaresupport.softwaregrp.com/ja/group/softwaresupport/search-result/-/facetsearch/document/LID/QCCR1J93476.
