Error in saving finalized form (Sorry, form saved failed! bad base-64)

Dear all, I am Phway Phway from Myanmar. Now I am facing with difficulty in saving form and exit (after marked form as finalized). It showed me “Sorry, form save failed! bad base-64”, but it showed saved the file when click the ‘save’ bottom on the top bar. However, there is no file in the “Send Finalized Form”. Please help me. I haven’t ever experienced like that. (I used HUAWEI mobile phone to collect the data).

Thanks,
Phway

Hello @phway_2641990,
Did you have a look in previous postings in this forum with the search function? See for example https://community.kobotoolbox.org/t/forms-stuck-in-edit-saved-form/23266.

Could you, please, also provide the server you are using (OCHA or HHI) and which Collect app (KoBo or ODK)?
