I've found an issue with the re-flashing the firmware. There are 3 types to be flashed:
1) Firmware itself
2) Resources
3) Fonts
If I forgot about updating the fonts by accident I found out that the device is stuck in the "Cannot connect to app" message showing absolutely nothing except this message. The final solution was to download the APK with latest version of Mi Fit in the language of your choosing and using Notify App for Mi Band to update all 3 types of the data. This required several tries as on the second flashing (resources) my Mi Band 3 disconnected in about 43%. Fortunately those devices are not that easy to brick as they have active BlueTooth stack even when not working correctly. I spend last 3-4 hours figuring this out so I'm putting it here and it might be useful to somebody
Also, how was the firmware translation made? Is there any git repository of the original firmware to be modified? If so, I'd like to see the repo and potentially do the custom modifications to my Mi Band 3 device firmware. Another question - does anybody know what MCU is being used in the Mi Band 3 device? I was unable to find this information anywhere.
Thanks,
Mig

1) Vyřešil jsem to tak, že jsem udělal downgrade na verzi 1.3.0.8 a MF 3.4.6.8 (tato verze znaky nezkracuje)
2) U verze 1.5.0.2 a MF stab 3.4.6 jsem zkoušel
- různé zdroje (nepomohlo, ztrácí se znaky)
- ENG 1.5.0.2 a MF stab 3.4.6 (nepomohlo, ztrácí se znaky)
- různé apk pro SMS (nepomohlo, ztrácí se znaky)
- aplikace Tools, Notifi & Fit, Mi Bandage (nepomohlo, ztrácí se znaky)
- zkoušel jsem upravenou MF i originální MF (nepomohlo, ztrácí se znaky)
3) S největší pravděpodobností se jedná o problém MB3 - přesně - jeho firmware
- možná to dělá font písma pro notifikace
- nastavení velikosti písmen při zobrazení
- způsob zobrazení (statická mezera mezi písmeny x dynamická mezera mezi písmeny) - condensed (font, space)
1) I have solved this by making a downgrade to version 1.3.0.8 and MF 3.4.6.8 (this version does not reduce the characters)
2) I have tried with version 1.5.0.2 and MF stab 3.4.6
- different sources (did not help, lost characters)
- ENG 1.5.0.2 and MF stab 3.4.6 (did not help, losing characters)
- various apk for SMS (did not help, lost characters)
- Tools, Notifi & Fit, Mi Bandage (did not help, lost characters)
- I tried the modified MF and the original MF (did not help, the characters are lost)
3) Most likely, this is an MB3 problem - exactly - its firmware
- It may be a font for notification
- Set letter size when viewed
- display mode (static space between letters x dynamic space between letters) - condensed (font, space)

Už jsem to tím downgrade vyřešil taky, ale ten starší soft má taky mouchy. Jednak se zprávy občas nezobrazují celé (u delších prostě chybí konec, alespoň není text useklý v polovině slova...), taky zprávy z whatsapp nebo instagramu zobrazují nick nebo jméno kontaktu dvojitě (2x za sebou), druhak třeba rozsvícení displaye gestem má delší prodlevu atd.
