QGC 3.4.3 (iOS) urgently needed

can someone send me an (iOS) IPA file of QGC 3.4.3
That could be loaded between 02.2019 and 07.2020
The appstore now only offers 4.0.10 and 3.2 (for old Devices)

Is there a possibility to replace V3.2, which is still in the iOS AppStore for backwards compatibility and has severe bugs, with V3.4.3 in the next QGC Major Update in order to have an executable older iOS available in addition to the current one?
Unfortunately, an IPA file for 3.4.3 does not seem to be available … and in iOS the 3.4.3 is the only version that provides all my needed features.
